The TSA is indeed embarrassing, but since we don't have audit data from the private security in previous eras we don't actually know if things are getting better or worse. There is also the notable fact that airplane-based terrorism in the US is now extraordinarily low, significantly lower than before 9/11. The causality here is hard to disentangle. In any case, I purposefully said "tightened" not "improved". All I need for my comment is that the rules have become more stringent since 9/11 (e.g., shoes off, no liquids, etc.), which is obviously true.
