I have experienced violent muggings myself, witnessed violence/assaults, sometimes even without reason or purpose, in Brazil, specifically Rio/Sao Paolo, Oakland/South Berkeley(during the early/mid 2000s before the tech hit), Bogota, and Medellin. I lived years in Mexico(CDMX/tlalnapantla) and experienced all but the most opportunist crimes, like pickpockets, and nonviolent crimes.

Contrast that with living in a very poor neighborhood in Chisinau, in Moldova. Iasi, in Romania, Kiev, and Saint petersburg. I never really felt in danger at all, I could walk home at whatever hour, go on a walk, take out my cellphone. The closest to being dangerous was desperate drug addicts in St. Petersburg.

These places/slums in eastern europe are just as poor, have the same problems with the same drugs. But the level of random violence in 'diverse' places just doesn't exist. I know it sounds fucked up like I am a fox news anchor, or something, but it is just something I have noticed.

It seems the more monoculture a society is the more safe it is in the poor areas. Specifically Europe, Asia, and the middle east. I don't know how to explain it without sounding like a racist so I wont.
