So the telephone briefing is preferred because it's more likely to be
incomplete?

Yes.

"All available information" is the way lawyers beat their opponents to
death. That's what a machine briefing gives you - reams and reams of
stuff that doesn't matter or says the same thing, and you have to read
through it all to find the one or two bits that do matter.

With a telephone briefing, I'm dealing with a person who has been doing
this all day, and is already familiar with the situation. I get the
picture without the noise.
