Again, the police in the UK and most of Europe are far better trained than those in the US. There aren’t going to have a baton out waiting for someone to open a door.
i challenge you to find some reports of UK police killing people on routine callouts unprovoked. Then compare that to the what seems like a weekly occurrence of such incidents in the US and control for the population difference.
There is little to no chance a person would be killed or even injured by the police calling to their house over a noise complaint in the UK. It just doesn’t happen. You simply can not presume that America’s dysfunction is replicated everywhere.
