View Full Version : Stupid Attorney taling about GPS's


Gerald Sylvester
February 18th 04, 02:52 PM
I never read anything about this Scott Petersen murder
trial before. I saw a headline about a "GPS." I started
to read it and I guess the guys car had a GPS in it
and the prosecution is trying to place him at the murder
scene. Well the defense attorney is saying the GPS
is inaccurate due to a malfunction and made the
moronic comment of:
-------------
Peterson's attorney, Mark Geragos, argued that the information gathered
through global positioning system technology was not accurate. GPS uses
signals from dozens of satellites to show a receiver's position to
within a few feet.

"If the FAA will not approve GPS for the landing of an aircraft, how can
a court of law approve its forensic use in a capital case?" he said.
--------------

I don't know if they are approved for auto-landing but
I'm fairly certain it can get me a few hundred feet AGL
on the exact glideslope of an airport 8000 miles away.
I'd generally consider that accurate enough. <grin>

My handheld GPS-V for my car has lead me to within a few
feet of the front *main* door of places in Amsterdam, Rome,
New York and San Francisco. I'd generally consider that accurate.

Yea.. I caught that in the news too... Either the attorney is stupid, or
he is intentionally lying to try and save poor Scotty's ass.. Maybe the
prosecution should subpoena an FAA representative to refute those
claims. Of COURSE they mouthpiece is comparing apples to oranges. Cars
use GPS primarily for horizontal guidance. They are quite accurate in
that regard when they get a good signal. What is it.. within 10 feet now
with SA turned off for the past few years??

Airplanes get the same great horizonal guidance, and GPS has been used
for YEARS and approved in an enroute, terminal and approach environment.
The only thing keeping GPS from being used to "land airplanes" is the
vertical guidance component. 200 Feet astray from an airway centerline
is no biggie. 200 feet low on a precision approach to minimums is likely
worth a paragraph or two in the obituary section. I guess thats why all
the big fuss about WAAS, LAAS, RAIM and other cool terms like that.

I havent seen a single car crash proven to be caused by the GPS showing
the wrong altitude. <grin> Likewise, just cause GPS isnt able to give
precision approach quality vertical guidance to the whole of aviation
just yet doesnt mean its not accurate enough to show what 100 square
foot block of land poor Scotty's car happened to be in... or how many
times he parked near or drove by where they found his wife and kids
body.. Poor Scott didnt even know the cops had planted covert GPS
recievers on each of his 4 vehicles when he did all this. The next crop
of cell phones will be able to help you be tracked pretty closely too.
The ability was legislated so enhanced 911 systems could locate a
caller. The same ability can be used to locate a suspect. The moral? If
you are gonna do something bad, turn off your cell phone for a while :)

Good call on the judge allowing the evidence.

Wow.. big rant this time.

Unaugmented GPS is accurate to within 7.2 meters longitudinally.

All the prosecution needs is a Professional Land Surveyor, as registered by
the State of California. At that point Scott's Attorney would be well on
his way to giving testimony illegally.

1. Attorneys do not "give testimony".
2. There's no law against attorneys making false statements. They aren't under
oath.

Uhhhh, guys?

The GPS was placed on Scott's car by the police; it wasn't a factory
install.

The argument was that the antenna wasn't properly located and the evidence
flawed.

But the judge just said the prosecution could use the GPS evidence...

The technique is known as "casting a shadow of doubt". It works
wonderfully well. Jurors eat it up. He's doing his job.

How did the GPS units installed in Scott Peterson's car transmit the
location information back to the police?

Some kind of continuous real-time transmitting capability? (Is this
built into the GPS system itself?)

Or did they have to surreptitiously recover the units from time to time
and downloaded data stored in memory? (And if so, are such units
available to the general public?)

The GPS system doesn't care.

There are several commercial tracking operations in business providing
the service. There are different methods of obtaining the tracking data.
Some are realtime transmitters, others are via interrogation.
Some services on high value rental cars will remotely shut the engine
off when the vehicle gets within so many miles of the Mexican border to
prevent auto theft.
Others, like OnStar, can detect airbag inflation, unlock car doors, etc.

And as a further comment, why would he not think that? Juries are made up of
people who have nothing better to do than watch Oprah. Not only that, but
they actually believe the idiocy spewing from people like Oprah. Anybody
smart enough to actually do something productive for a living either is
excused from jury duty or is excluded by an attorney who does not want
anyone with critical thinking skills on the jury.

The last time I was in a jury pool I told the judge the truth when he asked
whether I would serve on a jury. I told him that no attorney would accept my
presence on a jury because I had an IQ greater than that of a meatloaf
(granted, it is not a lot greater). I said that I had been called for jury
many times and that I had never been allowed to serve on a jury for that
reason. He agreed and excused me, somewhat to the discomfiture of those
already selected to the jury.

The jury is made up of your peers only if you are a complete moron.

In fact, laser based surveying is the accepted means for accurate surveying
measurments in California Courts.

I just say, "I am a registered professional engineer" and they tell me to go
home.

I think the prosecution can afford to stipulate to the 7.2 meter maximum
error. (unaugmented)

My data comes from GPS World, a source far far superior to the WAAS peddlers
at sat.geo.satellite-nav. The sat.geo.satellite-nav newsgroup is known to
be dishonest WRT GPS.

You are inaccurate in several respects. Clinton's license was suspended
for a specific period of time; he was not disbarred. He negotiated a
settlement with the Arkansas bar which had served him with a grievance
complaint for giving false testimony in a _Jones v. Clinton_ deposition.

An attorney who knowingly misleads a court violates the canons of
professional ethics and is subject to discipline by the court and the bar.
He does not have to be under oath. However, if an attorney gives
materially false testimony while under oath he is also guilty of perjury,
ordinarily a felony.

No, Clinton was disbarred for his Attorney giving false testimony in Federal
District Court. If the Jones v clinton lawsuit had been reopened, clinto
would have forfeited his Attorney client rights.

If your Attorney gives false information before the Court and you are aware
of it, Arkansas Law holds the client liable.

Dennis O'Connor
February 18th 04, 06:55 PM
Ahhh Gerald, you are confusing common sense and common knowledge with an
American court room... For GPS to be introduced into a capital case there
either has to be a precedent ruling at the appellant level on it's
admissibility (I am unaware of any such ruling), or experts have to be
called to testify so that the judge can rule on admissibility in this
case... This for your and my protections, not just this Scott guy...

Unfortunately, this is a big game of 'gotcha' where each side tries to trip
the other up, not on the basis of scientific fact, but on the basis of, 'you
forgot to say mother may I'... Scott's Lawyers have a good bet going, for
excluding the gps/lo-jacker readouts... Look at the courts recent
revisiting of finger prints because a sharp defense lawyer realized there
never was an appellant level ruling made on the science, in spite of a
hundred years of acceptance by the courts... Look at the humbling of the
FBI forensic lab, whose preeminent expert proved to be a liar and a
charlatan...

OTOH, jurists insistence of ruling on the basis of rulings made a hundred
years ago, in totally different areas of science long since disproved, as
the basis for their current rulings, forms a vast LaBrea tar pit for pilots
accused by an FAA inspector, and is directly why the FAA/DOT can rule
against a pilot and then appeal to themselves if confronted... This ruling
made long ago about the courts deferring to the FAA (CAA in those days), and
long before numerous more recent rulings limiting the power of the
government to avoid judicial revue, continues to allow federal judges to
turn a blind eye to the FAA/DOT's daily violations the constitutional rights
of pilots... And now Secy Ridge continues the 'family tradition', of raping
any innocent who blunders into a TFR.....

Anyway, back to Scott - guilty or not? I suspect that 99% say guilty...
But 99% thought Rep. Condit was guilty in the Chandra Levy case during the
early going, yet the place and manner of the finding of her corpse now makes
his guilt unlikely... And how many convicted rapists are now being found
innocent by DNA typing...

I would think he would be questioning what business the police had tracking
Peterson's whereabouts AFTER the crime was commited.

It seems the prosecution is trying him with character assasination after the
fact rather than with evidence of the crime itself. He'll probably wind up
being the first person executed for having an affair.

As far as Clinton goes, it's ancient history. Get over it. Move on. Get

Even WAAS will not "land" an aircraft. GPS supports non-precision

WAAS adds little to no value to aviation.

The CNX-80 demonstrates the rip off WAAS is. (not a complaint about the
CNX-80)

False.

The convergence of the GPS Jacobian does not occur for the conditions you
describe. One of the major advantages of GPS over current ground based
navigation is the difficulty of spoofing the system.

I suggest you read your "GPS World" issues some more. Improvement of
integrity monitoring was one of the main reasons for requiring augmentation
of GPS. Evidence already presented in this court case also indicates
some of the problems cited above which resulted in momentary errors of
miles rather than meters.
I'm an advocate of GPS navigation but it is not infallible and carries no
absolute 7 m accuracy guarantee.

False.

The failure to monitor the integrity of the WAAS signal is why the test bit
remained set until recently. The integrity issues were WAAS integrity
issues with no relevence to GPS.

Unaugmented GPS has insufficient integrity monitoring.
http://www.cts.cv.ic.ac.uk/html/ResearchSeminars/seminarDetails.asp?seminarID=62
:
"The assessment results also indicated that the current GPS system cannot
meet the RNP in most of the cases and the current integrity monitoring
mechanism is inadequate for providing the necessary integrity monitoring
capability. Therefore, this study suggests that augmentation systems are
needed to support the navigation function for all phases of flight." Jan.

The "Standard Positioning Service Performance Standard," Table 3.6
http://www.navcen.uscg.gov/gps/geninfo/2001SPSPerformanceStandardFINAL.pdf
gives the post-SA specification for horizontal position as being within 13m
95% of the time assuming the receiver can see all signals from satellites
above the horizon. The vertical spec. is 22m, 95% of the time. Actual
performance has exceeded these specifications but AFAIK the specification
has not been updated.
Feel free to cite any GPS specification that guarantees 7 m accuracy 100%
of the time regardless of reception conditions.

Huh,

Since the original report, there has been a second news release after the
defense got the actual records from the prosecution. In several instances, the
GPS readings had Peterson's truck at two different locations hundreds of miles
apart in 6 or 7 minutes, at an equivalent ground speed of something like 260
mph. The errors occurred often enough that the defense thought they ought to
challenge all of the GPS data. Another problem was the GPS transmitted
constantly to the police through cell phone connections which may have distorted
the data.

All the proceeding comments were taken from TV media reports, so take their
accuracy with a grain of salt.

Not following the trial but....
What's wrong with that? It's common for them to watch someone. What they
do can speak volumes even if it is not admissable it might lead them to
something else.

The defense should just keep casting doubts. Those doubts will stick in the
jurors' craw.

The guy has been tried in the media and found guilty. A lot of what they have
sounds circumstantial. There are a few twists to the case that are unusual.

His name was on a list of suspects that the police talked to about a missing
co-ed while he was at college.

There have been other cases of pregnant women that were killed and have
not had much attention at all.

Well, that's how a defense attorney earns his cat food. I rather liked
the quote :)

(Note that the bit about "dozens of satellites" was almost certainly
written by the reporter, and is not a quote from the lawyer.)

I was stopped by the police on my way to a flying lesson. The copper

I looked at the link you posted. It seems to be a summary of what is
intended to be presented at a seminar, with no associated evidence. It is
also not clear as to what Shaojun's definition of "inadequate" is.

It is not clear to me what method of integrity monitoring is going on in
the British airspace to which Shaojun refers, but it seems to be
unaugmented RAIM.

The summary indicates that his study "route" was London to New York. But
my understanding is that trans-oceanic flights have to have multiple
navigation systems, only one of which can be GPS.

That's a preposterous analogy, for a couple of reasons:

1) How many off-topic posts do you see on this newsgroup spontaneously
complaining about Nixon? I can't think of any.

2) Nixon slaughtered hundreds of thousands of South Vietnamese because they
had the temerity to defend themselves against a US invasion, as they had
done previously against the French and the Japanese. He subverted the US
constitution by using federal agencies to commit crimes against his
political opponents. He resigned the presidency in the face of imminent
overwhelming votes for impeachment and conviction. He would have gone to
prison (as did 25 members of his administration, including four cabinet
members), had he not been preemptively pardoned by his own former vice
president.

> Far from "getting over it" or "moving on," I would say: "Those who do

Good principle, preposterous instantiation. You think it's important for
people to continue to complain to an aviation newsgroup about Clinton's sex
scandal in order to protect the Republic from the possibility that another
president will get a blow job and lie about it?

And with term limits the populace will vote in the same characters with
different names.

Until the authority to spread money and favors (an authority they never
really had) is revoked, expect more of the same regardless of who is in
power or how many terms they (self)served.

Intentional jamming of GPS is difficult for newer units, as a simple filter
algorithm will remove most jamming signals. Do you know the difference
between spoofing and jamming?

Interesting... Must be local... Just this past 6 week jury session our very
well known circuit judge, had to cancel trials so he could sit on jury
duty... After having sat on two cases, and not dismissed by preemptory
challenge, he was then relieved by an alternate for having completed his
jury duty, and went back to his court room... In a newspaper article he
said he found it extremely interesting to actually get to sit in the jury
room during deliberations as he is barred from there otherwise...

Nope, but a salseman needs to sell. If you look at the difference in
minimums for the VNAV, you will note that WAAS gives the operator little to
nothing in increased capabilities.

WAAS was a scam run on aviation to remove tens of $billions from the
aviation trust fund; from that perspective WAAS is a tremendous success.
WAAS is the reason sci.geo.satellite-nav is a discredited and dishonest
newsgroup. Ron Lee being a possible exception.

Nope. Only good thing about Nixon, was , he got things done. The end does
not justify the means.

Remember, he got nailed for a coverup, of an operation he did not authorize.
He was too protective of his own people. He should have fed them to the
wolves, then he would have gone down in history as a great president.

The actual news article goes into this detail. After Laci Peterson was
reported missing, the police department placed covert GPS tracking
devices on all of his vehicles and monitored the vehicle (and therefore
Scott's) whereabouts pretty much constantly. This explains how they
thought he was headed for Mexico to flee the country. The defense
attorney is trying to get this surveillance data thrown out/disallowed..
and in trying to do so invoked the claim that if GPS wasnt accurate
enough to land airplanes, it wasnt iron-clad enough to be used as
evidence in a capital case.

The equipment that was in use for surveillance on Mr Peterson.

be a good idea to be familiar with the context its being discussed in?

At the time the devices were PROBABLY placed, this was a missing persons
case, and Scott was PROBABLY the prime suspect. The police (and I'm sure
a judge agreed at some point) were trying to surveil a suspect by using
these devices.

but... thats just speculation on my point.

No, but I am sure you will enlighten us. I have a fairly good idea, but I

GPS is a spread spectrum hahn waveform and has good resistance to
interference.

I could not make that same specific claim for the data link used by police.

Well not to start a legal thread in R.A.P but here is another
great one I read about in an article about the
Martha Stewart trial:

<begin>
Under cross-examination, Bacanovic's lawyer, Richard Strassberg, tried
to shake up the ink expert's credibility by saying, "You are aware of
the ASTM standards for ink analysis."

"Yeah, I wrote them," Stewart replied. The courtroom burst into laughter.

As a side note to your comment, When I was an officer on patrol, I
was out by the airport running radar when an F-16 was doing low
approaches. Curiousity got to me so I pulled the radar out of its
mount and got out of the car and pointed it at him. Once he got into
my range (speed or distance, I dont know because it started reading
199 which is the highest it will go) I started clocking him, If I
recall correctly as he was about to execute the missed, he was doing
about 140mph. I sat there for a little while longer to watch him
come back again. I again started tracking him with my radar. My LED
readout then showed JAMMED. I had to laugh as I could just see him
shooting me the bird as he flew by.

On its face, this is a bit disturbing. Did the police have the sanction
of the courts before emplacing these devices? If not, it smacks of
unlawful search, etc. On the other hand, if a court issued the moral
equivalent of a search warrant permitting the use of them, he's just in
deep doodoo...

There is a story I have read that concerns a couple of english constables on
road patrol near an RAF airbase... As a pair of the base's Tornados in tight
formation, came low along the road, the officers tilted their dash unit and
got a radar speed reading <well above the posted limit obviously>... On a
lark, one officer drove out to the airbase and asked to speak to the flight
commander... He then advised the officer he wanted to give the pilots a
warning ticket for speeding...
The flight commander laughed and said the pilots had mentioned that they had
a sudden 'radar lock alarm' on their ECM panels, and the only reason the
officer was able to be there was that their ECM Auto Protect was in standby
mode, otherwise he would have gotten a HARM missile (high speed
antiradiation missile) up his <ahem> radar gun...

Don't know the truth in this story, but it is amusing...

Well, I will, in any case. Jamming a signal blocks it in such a way that it is
pretty much useless. Jam the GPS signals, and your receiver can't tell where it
is. Spoofing signals causes the receiver to report an incorrect location while
"thinking" that everything's working correctly.

Check Popular Mechanics and the other magazines like that. I've seen
them advertised in some of the pubs.

That being said, any device that radiates is illegal without a license
(which you cannot get) so you will go from the frying pan into the
fire if caught with a jammer :o(

A number of years ago I designed and built a corner reflector system
that was rotated by the wind stream as the car drove along. It rotated
at a speed based on wind stream and the theory was that it would
reflect the radar signal back to gun and show an off scale reading. I
also tried a slower speed so the returned signal would show a lower
speed than vehicle actual. Since the signal being reflected was the
same principal as the return from the vehicle (no active radiator) it
would be legal.

Bottom line, I found that if I made the corner reflectors a reasonable
size, then they did not reflect a larger signal than the automobile.
They would have had to been so large to work they would have been
impracticable to mount on the automobile (front bumper, etc.)

My device was wind driven and had a rather slow rotational speed.
Maybe one of these days will modify and drive the system with a 12V DC
motor and gearing to get a rotational speed of 5K-10K so effective
area will exceed the return from the automobile reflective area.

Interesting project and may one of these days do some further work on
other legal methods of blocking/modifying radar gun signals. <G> Have
also been making some napkin drawings of using the Luneberg Lens
principles. Also a method of shifting the radar return frequency
(passively) to give legal speed readings (or a zero reading on
officers gun).

Now what does this have to do with flying. System could be placed on
aircraft to change (augment, eliminate or modify) return.of pulse type
radar.

I'm quite sure if the action was even bordering on Mr. Peterson's rights his
attorney would have been using that to get the tracking thrown out.

This is so very true but most lawyers I believe tend to forget this
rule sometimes. Another story while I was an officer, I had to attend
a DWI case that was finally going to court after about 3 years. While
I was up on the stand, the defense attorney was asking me questions
about the reasons I decided to take the defendant to jail. When the
question about his speech came up. The attorney made the comment
about his dialect and the part of the state that he was from and asked
me if I took this into account. I told him that I do take such things
into account. He then asked me "So officer, How many people do you
know from XYZ, Texas". At first I thought this question was a joke.
I then looked over at the jury and gave my answer... Well, including
myself and my family and all the people I went to school with as a
kid... A whole lot of other people! The jury rolled. The attorney
sat down and had no further questions.
The defendant was found guilty.

The attorney's job is to protect his client. 90% of law is procedural
and most cases are won/lost on procedure. Perhaps he's afraid the GPS
will put his client at the location. However, I'd be surprised if the
GPS actually kept any data.

As I understand this, the GPS devices were put on his car to track his
movements AFTER Laci was missing.

I don't see how that can place him at the scene. It can only support the
evidence of his affair.

I would not be so blindly confident in his attorney's attention to detail.

How would you feel about the police secreting a GPS tracker on your vehicles?
If they were doing it on their own recognizance, I'd expect information
so gathered to be tainted. If they convinced a judge that it needed done,
they would be on firmer ground. ...and tame judges can be found in most
jurisdictions.

According to one news report, the GPS log supposedly shows that he twice

In this case there are multiple attorneys working for his side. I'm pretty
sure if there wasn't a warrant or some pretty strong precedence on the
matter somebody on the defense team would have though of it [We did] or had
it brought to their attention.

Oh gawd, blew his own cajones off, right in public... That's hysterical...
In a previous lifetime I spent time covering the jail, so I got to hear, and
see, a lot of stories...

One night I'm working the hospital ER, the jail crew brings in Juan, who I
have seen at the jail a number of times, trussed up like a roasting
chicken... Seems he got into a punch up with the guards over something or
other..He has a cut on his head and some on his hands I need to sew up... I
tell them they have to remove the cuffs... They are incredulous and tell me
he is a bad ass and he will punch me... I insist and finally they do, and
stand back smirking...
I lean over Juan and I say, "Juan, if you punch me, you know what I am going
to do?"
Juan looks at me with a steely glint in his eyes, "What you gonna do, doc?",
he challenges me...
"I'm going to fall down and bleed all over you.", I say, wagging my finger
under his nose...
He blinks a few times, then his lips start to quiver, and then he snorts,
and finally he becomes helpless with laughter...

After I get done suturing his cuts, and the guards put his cuffs back on and
link them to his ankle bracelets, and are ready to lead him out, he looks
over at me...
"Hey doc, you OK for a grrriingo... Anyone gives you trouble, you let me
know... I weel take care of them." And out he went...
About a year later I saw in the paper where he bled to death on a street
corner...
Kind of spoiled my day... He was sociopath but he could be likeable at
times...

Did he know about the GPS in his car? ****, if he did I can't imagine
he'd be that dumb. There is evidence that this isn't the first time
he's done this. Another girl he was interested in about 10 years ago
also disappeared and was never heard of again. Sounds like he's a pro.

You should be naming JFK and LBJ for the killings in Vietnam, not Nixon.
The war was winding down when Nixon took office.

Really? That's why it took six years and the biggest demonstrations ever seen
in the U.S. to get the ******* to honor his campaign promises?

On the contrary, Nixon greatly expanded the US invasion, secretly (from the
US public) bombing Cambodia, for instance, unleashing thousands of B-52
sorties there, often in heavily populated areas.

But yes, Johnson was a monstrous war criminal as well--though I can't
imagine how you think that exonerates Nixon. They each inflicted far
greater atrocity than Saddam Hussein ever did.

The Ho Chi mihn Trail was through the jungle and bombing it saved thousands
of American lives.

Nixon took over LBJ's war, after Lady Bird's company had made hundreds of
millions of dollars on Vietnam. If you want to know who killed JFK, just
follow the money.

GPS evidence proved that Scott Peterson, who was falsely accused of
murdering Laci, was concerned about the course of the investigation.
As a matter of fact, he evidently went to the Bay, more out of
disbelief about the course of the investigation, than out of fear that
the police would discover his wife's body. When Scott Peterson went to
the Bay, he only stayed 2 or 3 minutes each time, and that is clearly
not a man who was concerned about what the police were doing. The
police had already shocked and isolated Scott Peterson by treating him
like a guilty suspect, and Scott didn't need any more than 2 or 3
minutes to confirm the fact the police were not investigating the
disappearance of Laci, they were merely seeking to confirm their
suspicions at best and pursuing the leads that the real murderers were
advancing, at worst.

Perhaps the police are angry at Scott Peterson because he was aware of
the fact that they were tailing him to the marina and having made fun
of them, they think that GPS tracking devices prove that the police
essentially duped a confession. They did not.

Since when is Scott denied the opportunity to observe the
investigation into his own wife's murder? -- if anybody cares to call
tailing Scott Peterson, an "investigation". In the final analysis, the
police were tracking Scott Peterson when they should have been looking
for Laci, and they are pursueing Scott at all cost, to evade the
simple truth.

Six years?

Nixon took office in January, 1969 and the "armistice" was signed in
January, 1973. That after three years of gradual withdrawal. It was
Operation Linebacker in September, 1972 that brought NV back to the table
(for real) and the war ended within about four months.

It was 1975 (six years later) when the North violated the armistice and
overran the South. It was then we had Kerry's "peace" and the result (IIRC)
was 500,000 to 1,000,000 deaths in the "re-education" camps (more than
actually died during the fighting).

Tom -- one of the last ones out in March, 1973

Not to mention the slaves delivered to the Soviet Union to settle Vietnam's
debt.
