Also Sierra Leone in Africa with a homicide rate a third that of the USofA.
Both Ghana and Sierra Leone are gated communities, just as the USofA, the UK, and Australia are.
I'd suggest that Woodmore fails to meet you particular bias, hence you rule it out.
Woodmore likely meets your four intended criteria depending upon the level of internal surveillance .. I suspect it's not surveillance that prevents Woodmore occupants from killing each other.
Gated communities don't count because residents have to be wealthy enough to buy their way in, so they're populated by a non-violent-criminally-biased sample of the general population. Some countries might count as gated communities if they're heavily populated by 1st generation immigrants who had to be wealthy to get in, otherwise no, they're just full of whatever random people were born there or moved there without any selection pressure against crime.
