I’m not so sure the TSA people would give a crap if you missed your plane because of all the opt-outs.
TSA is a make-work program for high-school drop-outs and a way for the government to exert arbitrary power over the peons.
The TSA Should be abolished. The "Department of Homeland Security" should be abolished and the Patriot Act should be repealed. The purpose of those things is to empower government at the expense of the people.
But if I know FReepers, the response to the above will be something like "You and your talk about power and people and government sound like Islmaofascist-communism. Do you want Osama bin Laden to give you a rough pat-down? I bet you'd like that!"
