Nothing new. These same ideas were being floated about in 1968.
Now, let me tell you how it should be done. Give a warning, “Turn your guns by such and such a date or else.”
Then descend on that town with house to house searches. Anyone with a firearm is immediately shot.
Then go to the next town, do the same. By the third town you will find more and more guns piled up for confiscation.
Never discount the influence of a wife on her gun owning husband.
Or the citizens could fire on the “police” doing the searches but then the Government could claim such towns are in insurrection against the Government, then they could bring in the Army to do the dirty work.
An attempt to do so would result in State sponsored civil war declarations, and a military coup against the Federal government.
But anarchists can dream on...
By the third town you'd hear the 2nd shot heard around the world.
