I'm kiwi, but from the time I've spent in the US, and with US citizens it's seemed to me that the expectation of confrontation possibly escalating into gun based violence makes for significant behavioural changes.
Sometimes that's about forms of politesse, and sometimes it's about knowing, and choosing to put your body in the way anyway.
One of the things that seems to be missing from more of my European friends is the everyday concrete understanding of the consequences, and of the choice to step up.
Then again, the US acquaintances who've been more 2nd amendment aligned, generally have shown little respect for unarmed resistance.
Should Europe be tested, I'm not at all certain we'd do as well.
