Every time I go through the TSA (and I must for my job) they are more disrespectful, more attitudinous, more smart-assed, more calloused, more groping, more surly.
Of course they are Feds and this is a local cop issue but the point is, as you said, they, regardless of what level of 'gubmint' have infinite money, infinite protection from the courts, and a fundamental dislike of the citizenry.
History tells us that the more power they get, the more tyrannical they become. It's just plain old human nature. It's why America was founded.
We gotta get ALL these dogs back under the porch.
The big difference is this:
Things will change if the cops ever no knock the son of a prominent politician or functionaries house and kill him. Until that happens nobody really gives a shiite about Joe bag O donuts working at the mine.
No Knock warrants have to end. But somebody “important” will have to killed to change the practice.
