Maybe a few understand that. Certainly corrupt politicians in big cities have had that fear.
The Progressives have always hated any restriction on government power. They believe an restriction is immoral, even evil. The Second Amendment is seen as an abomination which needs to be neutered or eliminated.
Goes with the fact that government is the god they worship. I wonder how long it will take them to ignore posse comitatus and start using the military to round up civilian weapons considering they've already massively ignored the 4th amendment with the ban on evictions, and wiped their backsides with the sixth amendment's "Speedy trial" with the people who were at most guilty of trespassing on Jan 6.
When you come right down to it, who's going to prosecute the government if it violates the law and the constitution? Are any of the govt prosecutors going to jail for violating the Jan 6th's detainees' 6th amendment rights? (Sometime after hell freezes if at all). The only real check on government's use of force is the potential use of force by the citizens against the government.
