Exactly.

This isn't new. The TSA started out with puffer machines, which aren't influenced by emotions like sniffer dogs, but they whined and moaned and complained that they were getting clogged up and were too hard to maintain. So instead, billions were spent on more jobs, and scanners that aren't safe to use and can't detect the threats they're trying to address.

Meanwhile, Toronto's CN Tower uses them on every guest who goes to the observation deck. I've been through, and they're kind of fun - search YouTube and you'll see lots of smiling faces. That and they don't harm the customers and can actually detect legitimate threats.

I've discovered and been following the "Boycott Flying" group on Facebook lately because they seem to cover a lot more of the topics with regard to TSA safety that either don't appear here anymore or get deleted; it's a great resource. But I was a little surprised how everyone pounced on the idea of puffers on there too - this is the kind of thing we've wanted all along! Unintrusive, safe for health, dignified, and actually can detect new threats for a pretty good cost/benefit ratio.
