If I had to guess, it will be “Fusion Centers”, such as used to combat terrorist, where the FBI is set up to work with the local police.
My guess is the Fed gov would strong arm local and state police through such joint projects to do the actual legwork on an individual basis.
It will probably be a carrot-stick approach, where the threat is to pull free Federal goodies.
My guess would be it would be done piecemeal at first, done to a few people to try and intimidate the vast majority of people who don’t want to cooperate, by making an example out of a few.
For example, 15 local police & SWAT show up with maybe one FBI guy on site, and they do a “no knock raid”, kick your door in and take your stuff. If you resist, they shoot you. Then your obituary gets published later that week.
Hmm...giving your post a lot of thought. Interesting....
What you’ve described, though, is a strategy and not a legal basis for action. The latter must come in the form of legislation or executive orders backed by the legislative branch.
So...who sets up the fusion centers and under what authority? States don’t necessarily knuckle under to the withholding of Federal monies, and dragooning local LEOs would turn them into ‘enemies of the people’.
It would require a very pliant Governor & state assembly. Does the Federal government have enough tanks & aircraft to dominate fifty states?
Frightened gun owners turning in their property en masse? More likely bullets will be flying in both directions. It doesn’t take much effort for even a couch potato to lock & load. Murdering one gun owner to make an example could have the opposite effect:
“Freedom’s just another word for nothing left to lose”.
