Airport Security

I was traveling this week and as always I considered the security that we go through to fly. There has been a lot of talk about adopting the Israel security plan. That got me to thinking, what if someone is really committed and coached and they don't muff one of those questions they get on the plane. The same with putting Marshals on flights. A Marshal has no better chance of catching the underwear bombed than initial security unless the bomber gets up and yells that they are going to blow up. Maybe then the Marshal can shoot them. A better idea might be to put soldiers and dogs in the airports. I would think that this would cause the would be terrorist to think twice about trying to board a plane. This would not be cheap but it might be effective.
