And the OP itself shows that this is a terrible idea. I'm sure that Boyd would have been allowed on an airplane with no more than a cursory glance if people took your approach.Right, or wrong, it's Islamic terrorists that pose the greatest threat, at this point in history, therefore that's where the focus is going to placed. That being fact, we can't get anywhere strip searching an 80 y/o maw-maw, when looking for Islamic terrorists. It may not be PC, but profiling persons to determine if they're a threat is one the tools that law enforcement uses to catch terrorists, or any other criminal.
Then airplane go boom boom.
