If it were upto me, we wouldn’t have such a car dependent culture. It is absolutely possible to invest in public transportation/multimodal transport and reduce this number significantly.
But to middle class snobs who think they're morally above it all, such dirtiness is a reality they can wave away with a dismissive comment of superiority, safe from all that messiness, in their nice suburb homes.
So long as they intentionally ignore these lower class facts that some wrongdoers exist who can literally only be stopped by deadly force, they can continue to put their chins up and lament the inferior-to-them simpletons who think guns have to be a thing, in between taking long savouring sniffs of their excrement after every bathroom visit.
Police worldwide, where guns are usually illegal, are usually armed.
