Once they get out of the cities, they are going to encounter people that are more heavily armed, more proficient in the use of said arms, and more conscious of the law. It’s a lot harder to make a case stick on someone who was defending their home, as compared to someone who goes out into the middle of a riot by choice.

What they've done when they've tried it before is camp out on someone's lawn (or on the sidewalk) and set off fireworks. Maybe every so often something that sounds like a firework is actually a gunshot. It terrorizes the people in the house, to the police it sounds mostly harmless, and the action probably wouldn't to a "reasonable observer" warrant lethal force since it'd be hard to make a case you thought your life was in danger.

These people have lawyers who tell them where the line is, and they are masters of going right up against that line to provoke you to do something they can get their lawyers to pressure the cops to charge you for. We need to be prepared for that style of legal maliciousness.
