Dianavan - An IFB is not the shape of the entire ear. It is basically a small mold that is used for the inner ear.
Here is an example of what it looks liek -earpiece

Makeup and placement of the device can hide it from TV cameras, but if he had one during the debate, you would see it. They walked around the stage and cameras were on all sides of them.

In addition, these devices do not have very much of a range. You need to be within about 50 feet of the transmitter.   Setting up such a transmitter in the building would not be very easy to accomplish.

Bush and his handlers may be stupid, but do you honestly think they would have left a bulky device on his shoulder blade knowing that cameras could pick it up? A breast pocket jacket would have been an easier place to hide it. The fact is, anyone in that room who got up close to Bush could have detected it. There is no earpiece that can be completely hidden.

What was it? I really don't know. I don't know enough about bullet proof vests, but that would be my first guess. The White House would not want to admit to his wearing a vest in the debate as a matter of security.

Look, I don't trust these clowns any more than the rest of you. I want to see Bush out on his ass, but this is not going to accomplish anything. I've been in enough in television studios to know that viewers can be fooled. In this instance, we are once again looking for a person on the grassy knoll or hidden away in Hangar 53. What we end up doing is looking like a bunch of kooks and completely missing the goal that needs to be accomplished.   You aren't going to get Bush out of office even if you do prove he wore an earpiece.
