Contrary to my original understanding of Europe, some countries there have a substantial amount of privately held guns. Unfortunately, very few of them permit defensive use. Even Switzerland has curtailed legal carry, leaving Czechia, Estonia, Lithuania, Moldova and possibly some of the ex-Yugoslav fragments as places where effective self-defense isn’t outright illegal.
With the rather exciting interactions between the locals and the recently imported criminals, I wonder how long it would take for the Maquis to re-form and start going after the easy but culturally acceptable targets. Given the tendency of government agents to look out only for themselves and sometimes for the perpetrators of the violence, Europe isn’t looking so great just now. Of course, it’s probably affecting only some areas, but the blanket refusal of the various governments to recognize their citizens’ right to even minimal self-defense is going to worry everyone. And the last time this type of thing was a problem, Freikorps ended up cleaning up Bolsheviks and everyone unlucky enough to get caught up with them. There might not be as much of a power vacuum now as there was then, but people can get pretty inventive when properly motivated.
