It is a race issue as
@Mirzali Khan said, why does 13% commit 52% of the violent crime?

You have cringe liberal logic, the real reason Black Americans are specifically so much worse is because on average they have very low IQ + horrible environments since childhood and they struggle to compete with their counterparts - all this combined makes it very easy for them to be sucked into crime. They are mostly violent and careless people who don't understand the consequences of their actions, they also pride themselves on being ghetto gangsters.
You can't compare blacks in Canada to blacks in America, generally those who are couple generations from Africa are much more better behaved because the culture they originate from is much better. Even many African people don't like to be associated with African Americans.
