I think part of the reason that the "erosion of freedom" is happening is because of those that just can't seem to control themselves. They have to tighten the noose farther and farther to try and prevent things like child pornography and under age sex and the like.

Unfortunately, what the law makers and enforcers don't realize is that the tighter the tie the noose, the more people seem to squeeze out of it. It's a valiant effort, but there is no real way to stop it. Not that I am saying that they should stop trying because there are some really sick bastards out there, but I just think that, in the long run, it's a losing battle.
