What still bugs me, is...last time I flew, no one looked at the baggage area.
I can came and went as I pleased, bringing my bag out then back in.
What if I had boom sticks in my bags and enter the baggage area from outside while it's busy?
who is going to notice that i never got off a plane ?
Taking out an airport terminal will get more people, say on a thanksgiving holiday getaway day, than trying to take over a plane.
I could tell you stories from firsthand experience when I was with DHS that would scare the crap out of you. Let's face it, anyone can still bring weapons of all types into an airport ticketing area. Many people do. No matter how far back you push the protection perimeter, there will always be a zone where people congregate for a security check and where they are vulnerable.
Same goes for taking out a mall, or a Wal-Mart, or a church, or a concert, or a sporting event. No reason to single out an airport terminal for special restrictions, unless it involves potential access to aircraft.
