Crime usually has root causes like poverty, inequality, poor education, etc.
If you look at Europe, the crime rate is much lower than in the US. Gun violence is near non-existent outside of gang-related crime.
Most of Europe would be deep, deep blue if transferred to the US political scale. They have heavy gun control and redistribution of wealth results in much less financial inequality. In turn, it causes much lower crime rates.
I don’t think US crime rates have anything to do with culture. It has to do with rampant inequality and easy access to weapons. Combine that with mental health issues, and you got a real toxic cocktail.
