They may have said it but it still doesn't make sense.

Of course it does. With a limited number of squawk codes, that limits the number
of aircraft that can be allowed in the area. With a requirement for flight
plans, that means that the authorities know exactly what aircraft are there. You
can keep out anything that you think is suspicious, and the military radars in
the area will alert you to anything that's not supposed to be there. In one
stroke, you eliminate all of the unknown radar targets, especially the ones down
around 1,100' squawking VFR. And if one does come along anyway, you can assume
it's hostile. From a security viewpoint, it's nearly perfect and the military
and Secret Service have been asking for something like it for at least a decade
(that info comes from the same hearings).

Were these "security people" aviation experts?

No. You are somehow under the impression that the ADIZ was set up for aviation
or by aviation experts? It was set up to protect the area *from* aviation. From
their viewpoint, we're lucky that anyone is allowed to fly there at all. These
are the same people that shut Reagan airport down completely. If they had their
way, it would still be closed -- opening it required tremendous pressure from
Congress.
