Those riots occurred in liberal, Democrat controlled urban areas in a relatively small number of states. There weren't riots in Miami, for example. There are plenty of videos of when the "protesters" started marching through smaller towns and suburbs, and a bunch of men and women stood outside with rifles just watching. There were no riots in those towns. And the police didn't hit the locals with truncheons for daring to stand on the street in opposition. Kyle Rittenhouse basically stopped the riots with a few well-placed shots from an AR, and he was acquitted for it.
In the US, it's all about where you live, who is the elected prosecutor, and who is the sheriff. If you don't like state sanctioned riots in Seattle, you're free to move to small town Indiana, buy a few guns, and never deal with them again. Correct me if I'm wrong, but there's no escape from people like Keir Starmer no matter where you run in the UK. If you even tweet the wrong thing, you'll be prosecuted and locked away while Muslim rapefugees continue to do whatever they want with funding straight from London.
Of course, there are bad things in the US. But the difference is that if a rioter tried to smash up my stuff in the state I live in, I will have the backing of the local police, the local prosecutors, and the state government to use my legal firearms in my own defense.
