The reason that racial profiling exists is because there are indeed crimes that certain races are more likely to commit than other races. Like, if you hear that there’s a criminal out there snatching gold chains or selling crack, you might be right to assume the culprit is Black.
Similarly, if you hear that there’s a criminal out there committing serial murders, starting maniacal religious cults, shooting professorial colleagues or flying single-engine airplanes into IRS buildings, a white suspect might be more likely.
Why the former listed crimes are seemingly treated more seriously than the latter mentioned crimes is anybody’s guess. But the tendencies exist more likely as a product of economic circumstances than because of any inherent biological differences between Black people and white people.
Everything else being equal however and you might expect that suicide rates between Blacks and whites would parallel if not, considering finances again and the general belief that Blacks in America have it so much tougher than whites and everyone else, believing that Blacks would be most likely to kill ourselves. Two very recent headline grabbing suicides argue otherwise however.
