If it were not for America’s “diversity” we would be living in one of the most non-criminal countries in the world.
While you think about thhat think about who is committing the crimes in the other countries of the world.
Is it the same people? In many cases it is.
I was at one point in an online debate about violence in America with a European woman who was going on about the US homicide rate being due to the easy availability of guns. She slunked off after I showed data from the California Justice statistics web site (most states, plus the feds, lump Hispanic crime under white crime -- California is one of the few states that break Hispanic crime out). The white, non-Hispanic homicide rate was around the European average, with Hispanic rate several times higher, and black rate twenty times higher.
Homicide rates correlate closely with ethnicity and culture.
