I've been hearing a lot lately about how purchasing your tickets and even checking your own baggage is moving even more and more toward the "self-service" route.

A lot of passengers seem to like this.

Then there's also the issue of the screening methods that airports use.

A lot of passengers don't like this.

Is it just me, or does the TSA not know what it's doing? It seems to me that letting passengers check their own bags is dangerous, to say the least, when it comes to security. And full body scanners and pat down just don't seem to be working at all.
