There is one reliable and consistent determinant for which groups of people commit crimes, and that is the incidence of poverty, unemployment, and injustice. When people lose hope, when they see the system as not cooperating with them and helping them when but rather antagonizing them and in opposition to them. When people perceive society as unfair and taking advantage of them. Then the idea of seizing their own advantage to the detriment of others starts to seem sensible. And it isn't necessarily a matter of moral decay so much as a matter of applied game theory.

This has been true for every ethnic group imaginable throughout history. In America it's been true of the Irish, the Italians, the Polish, the Chinese, and so many others. So many now celebrated "model" ethnicities. The existence of [ethnic group] gangs who regularly commit certain crimes at rates much higher than others is not a sign of the uniquely fragile moral fiber of [ethnic group], it's a signifier of their continued mistreatment by society and continued ethnically biased socio-economic inequality. Only a tiny minority of any [ethnic group] are criminals, to take the actions of a minute sub-set of a very large group of people as a bad mark against the entire group is entirely unjustified, especially in light of the issues I've described above.

I can't believe that it's 2016 and I still have to explain this.
