Republican presidential candidate Ben Carson says he is still waiting to see evidence of racial bias by police forces in the U.S.
Carson is the only major White House hopeful who is black. He made the comments Saturday at a justice forum in Columbia, South Carolina.
Carson was asked about high-profile cases of alleged police misconduct, including several in which African-Americans were killed by police or died in custody. The retired neurosurgeon says he is not aware of a lot of cases where police officers treat black citizens unfairly because of their skin color.
He says any "rogue policeman" should be punished but that society shouldn't set rules "based on bad apples."
He adds that he has never had problems with police because his mother raised him to "respect authority."
