Other than the fact that they're locking people up instead of levying ruinous fines how's this different from any other enforcer working on behalf of the a federal (or state) administrative bureaucracy?

The road to hell wasn't paved in a day.

If you can't tell the difference between a fine that you can go to court over and having masked thugs point guns at you, throw a bag over your head, and disappear you without due process, I don't think we are going to find a lot of common ground.

Enough of a difference in degree is a difference in kind.
