Of course, that means that when I travel, I take less stuff so I can carry it, or check at the gate for small planes.

Now if we're talking about common sense, there's a lot that the TSA is required to do that flies in the face of it. The liquid ban is utterly backwards. The people who were arrested for trying that were found out through detective work, not through security screenings, and most chemists say their plan was not very realistic. It's more dangerous to deprive elderly people of water and infants of pumped breast milk. The "Threat level is orange" announcements need to stop. The threat level has been orange since the threat level color code has existed. It's meaningless. The expensive body screening machines that look through your clothes, and are used more often on attractive ladies than suspicious acting people need to go away. We should be spending that money training FBI agents so we have more detectives stopping plots before they get to the airport, especially since there's no evidence that airports are a particular target. Stadiums, malls, and churches are more vulnerable than airports, and just as "good" terror targets. We shouldn't have to deal with draconian TSA-like security in all public places. Or even at airports. You prevent terror attacks through detective work, and infiltration, not be treating your citizens like suspects.
