Non-meme answer here from someone whose also dealt with these retards.

They are either an organic movement of idiot's like flat earthers and UFO cultists. Or more likely it seems like they are a psyop from a hostile foreign power designed to weaken the US through "lawfare", AKA convincing retards to frustrate and waste the resources of local and state law enforcement and to weaken peoples trust in the law in general. Don't do anything outright illegal to them but DO make it a point to dish out even more shit to them than they give to you. It's the only way to make them cut that shit out because they cannot be reasoned with. Their whole worldview is warped and nothing they spout holds up in a court of law. Don't cut them breaks, don't let them intimidate you, and don't lose your cool when dealing with them. They are banking on frustrating you enough that you slip up and give them an excuse to sue you. Outsmart them at their own game and ask them things like "are you refusing to comply with a lawful request?" If they claim to be complying but clearly aren't vocalize that they aren't complying so it shows on the record and after a reasonable amount of attempts bring the hammer down on them. Make sure that any footage they collect paints them as the unreasonable party and it won't matter if they take you to court.
