Seriously, this does present a thorny dilemma to the TSA. Let's suppose for a moment that they decided to ignore amounts of cocaine below 5 kilograms (from CATSA Screener's example, above). If a screener finds a block of cocaine, does he then have to weigh it to see if it crossed the threshold into prohibited territory? How about a group of travelers, each with 4 kilograms of cocaine? Are they OK, or is the amount aggregated for this purpose? You see how ridiculous this can get.

I have always been a big supporter of searching only on probable cause, but I really haven't been able to reach a conclusion as to how screeners should respond when they stumble across something obviously requiring that some kind of action be taken. I can't believe that a screener finding a human head, for instance, should just say, "Have a nice trip."

At some level, people who bring human heads and significant quantities of cocaine to airports deserve whatever happens to them. They are guilty of terminal stupidity at a minimum.
