My goal isn't to be 100% secure. Unlike the TSA I know that isn't possible and I see no benefit in pretending otherwise. I just want the money being spent on security to be actually adding to security rather than detracting from it. It seems to me that they could replace at least 2 people at every shoe sniffing checkpoint with a well trained dog -- simultaneously improving security and either decreasing costs or redeploying people to higher value tasks.
