Therein lies the rub...
Its very clear and evident to at least 1/2 of Americans that the federal government is irredeemably corrupt, the other 1/2 doesn't care, so long as the corruption is against orange man and his deplorables. That's going to be a real problem when normal Americans start viewing Federal agents nothing more than lawless Stasi death/imprisonment squads.
I don't even think it'll get that far. At some point violence, and especially violence against agents of the state, will transition in a lot of peoples minds from a strategic decision ("If I cap this cop it undermines the rule of law, and even though THIS one is being an ass, overall I like that folks are law abiding") to a tactical decision ("If I cap this ahole will I get away with it, or how many of his friends have to die as well"). That's a real problem for the government agents, because tactically there's not a lot of reason to put up with their *expletive deleted*it. And even if they "win" one citizens decision process, the next one could very well own some land and a backhoe.
They don't need to be Stasi or NKVD, they just need to be slightly more annoying than disposing of them.
