Communists fear law abiding, gun owning citizens.
They do not fear criminals, because they are criminals.
You have to look at England to see the big picture.
Socialism is theft, pure and simple. After the first socialist generation, more and more recipients started to eliminate the middleman by stealing directly.
At first, the thieves in the government tried arresting and punishing the thieves, especially if they killed their victims.
But after a while, the thieves in the government recognized that their brother thieves were simply a pursuing a more efficient way of dispossessing the Class Enemy. So, penalties became less and less, and resistance to theft was turned into a crime.
England is PARTICULARLY concerned when the thief is hurt or killed, because, if you allow that, the professional thieves who run the state may well be next.
New York, DC, Illinois, and some other areas/states are advanced kleptocracies, where the government thieves and the street thieves are engaged in a joint enterprise.
It’s really not too hard to understand, once you get it.
