If I have to tell my children that only mommy, daddy, their doctor, and oh yes, any government goon who flashes a badge can touch and rub their privates (and if you tell the government goon 'no' he'll sue and there goes your college fund) then we've destroyed our country far more effective than any act of terrorism could.

The U.S. legal system can be described as many things, but certainly not as having a firm grounding in reality.
