My opinion of all this security theater is that it is not actually designed to make people feel safe. It is instead that the people at the top know another effort by dedicated attackers willing to die can not be stopped. And I bet that they consider such an attack happening again pretty likely. When it does, the federal government wants a conspicuous example of what they were doing to keep us safe so that the population doesn't riot. From this perspective, the more annoying and egregious the security hassles, the better they are.
