Because most (not all) racism has vanished... they still discriminate against the poor and probably always will. Profiling happens because there are certain things police think are good indicators of criminal behavior like dressing in a gangsta fashion or covering yourself in tattoos and driving a fancy car while looking like that is something I am sure they train officers to look for. While the man in a pricey car but wearing an expensive suit often gets a pass because he has the money to fight back legally even if he is speeding. They also don't hesitate to pull over all poor people if they are breaking the law because it's easy money since they probably can't or won't fight back legally. Kids are often unfairly targeted to for a similar reason. I lived near a school for years and the cops would set up at the end of that street and ticket all the kids as they sped past. Kids don't fight back legally either.
