But once the raids start, things are going to get a lot more difficult and dangerous over the next few days and weeks for the people conducting the raids.
Are they going to set up a security perimeter hundreds of yards out from their raids? Set up counter snipers? Are they going to travel in armored convoys to/from their un-Constitutional confiscations?
Even worse - or more effective at stopping this un-Constitutional nonsense... Once word gets out that it is XYZ organization conducting the raids (be it local police, sheriff, etc.)...heck everyone knows where they live. Their neighbors all know who they are. These guys aren't dumb. They know there are lots armed people out there who would look at raids and confiscation as a triggering event.
How many times would a sheriff's deputy have to come home and find out someone had put a round into the quarter panel of his wife's car on the way home from picking up the kids from soccer practice? How many times would he want to wake up to flat tires on his car? A fake (water-filled) molotov cocktail tossed onto his porch? Sure, some would keep going, and it would end in bloodshed. Others would get the message right quick. The raids would stop due to "unavailability of resources" to continue them.
Without turning the US into cold war era East Germany there is no way they could enforce this long term. No way.
Effective message. Great screen name.
