A part of me thinks its rip-roaring funny. You just can't get away from the TSA. If you decide not to fly over the Thanksgiving and Christmas holidays, and take a train or bus instead, there they fucking are. Is it really that much of a stretch to think they might start patrolling the interstate highways if more people start driving to grandmother's house?
This is a perfect example of what happens when you grow government. See, I have this theory. If you resent government intrusion in your life, the government automatically adopts the attitude that you must have something to hide. It's an endemic, systemic, built in virus common to any bureaucracy, and it can only get worse.
But I don't think you have to worry about it getting to the extreme where the government is doing spot checks of your homes out in the middle of fly-over America. That is, unless a family of Muslims move into your neighborhood, in which case don't be surprised to hear a knock on your door. In that event, you your family and home might well be subjected to a government spot check. You know, just to be on the safe side.
Of course, it is highly unlikely that they will search the home and persons of your new Muslim neighbors. But you really shouldn't let that bother you either.
Remember, our country has a terrorist problem. Not a Muslim problem.
