Agree with all except #2. Air marshals increase the chance of an incident occuring by bringing a weapon on board. And several of these yahoos have demonstrated that they cannot take care of their weapon, or that their only response to even the mildest of "situations" is to draw their weapons. Also, they steal premium class seats, thereby stealing revenue from the airlines and depriving passengers of these seats.
I would trade every air marshal in for a device that does a chemical check on an entire person with no x-rays or strip searching. Several devices exist and could be implemented today, were the leaders of the TSA not criminally incompetent fools.
I also agree with public access to airside.

Dovster, remember, I've been espousing these ideas since black day when the TSA was created.
