It cant be done. Lets be honest, it just cant be. So, we do the best we can. The folks here spend hours second guessing that every day, mostly from ignorance. As I have attempted to show, security is a very complicated business, and few without experience or training can discuss the subject intelligently. The argument about dogs is just one case in point, some here claim that they are the answer to the TSA and all of our procedures and equipment, and they make these arguments completely from ignornace about the subject.

Because the threat comes in so many forms, and from so many different directions, the only intelligent way to address the threat is with a comprehensive and layered approach. Thats a basic idea, the very first one that must be acknowledged before the conversation can go any further.
