It partly can be explained through white privilege, as the law enforcement and judicial systems are designed systemically to screw over minorities. Racial profiling is a thing, and if you're black, a police officer can use whatever excuse they want to pull you over while driving, and if they can't find anything, they'll invent something (for example: planting drugs on you). When that happens, you're life is literally in danger. Many examples of this can be found - one just has to look at the racial makeup of the US prison system (systemic slavery). It goes really deep. The US is kind of in a state of being acknowledging this in a fundamental way, with the movement to defund the police.
