Slavery, Chinese exclusion act, Japanese internment, Jim crow laws, are just some examples of the times public policy was explicitly racist. A bunch more things are implicitly racist, with the war on drugs being one of them (interestingly one of Nixon's aides said that the war on drugs was essentially made to criminalize black people and hippies).
