I think TSA stands for "Temporary Sensory Assholes."
They put on a big show to give you a false sense of security, but those who have purposely tested them for efficiency have easily slipped a bunch of dangerous stuff past them.
Let's face it: When a real terrorist wants to hurt us in a free society, it will only be stopped by infiltration of their unit using all the dirty tricks necessary for such! Current tactics just scratch the tip of the iceburg and give TSA agents a chance to see nude women as they pass through the scanner!!! I want a job!
After-analysis of 9/11 shows we were stupid / could have caught them several times over / failed to exercise the standing order of "intercept and force down" any hyjacked commercial airliner. They flew over the most heavily Air Forced part of the country for some 45 minutes without interception =
they were told to "stand down!"
