Democratic presidential nominee Hillary Clinton vows she’ll tackle the racism in the nation’s law enforcement system.

“We gotta tackle the systemic racism, this horrible shooting again, how many times do we have to see this in our country?” she said in an appearance on the Steve Harvey show. Clinton was specifically referring to the police shooting of Terence Crutcher in Tulsa, Oklahoma, saying he had his “hands in the air” when he was killed.

“This is unbearable and it needs to be intolerable,” she said.

Clinton told Harvey that if the African-American community came out and voted for her, she would work to stop racial shootings by police officers.

“Maybe I can by speaking directly to white people say, ‘Look this is not who we are,’” she said. “We’ve got to do everything possible to improve policing, to go right at implicit bias.

Clinton was careful to specify that there many “good honorable cool-headed” police officers, citing the ones that successfully apprehended the New York City terrorist suspect in New Jersey on Monday.

But she restated her belief that something had to be done to fix police departments around the country.

“We can do better,” she said. “We have got to reign in what is absolutely inexplicable.”
