Airport security.

I've written about this before. I am on a watch list for airport checkin with Southwest Airlines (but not, interestingly, any other airline that I fly regularly). Having my name on that list has meant I fly the middle seat whenever I fly Southwest, because I have to check in at the terminal. Not deadly, no, but a hassle, and especially aggravating because the additional screening I undergo doesn't actually increase air security.

Further proof of the flaws in TSA screening appear in an article in CSO. Thanks to Bruce Schneier for the link.
