Sentinel president: We need more black police

Louis Arnold, the president of Cincinnati’s black police officers’ union, said Wednesday he hoped ongoing protests against police brutality would lead to more black men and women joining the force. He agreed policing needs to change, he said, but believes people within the system are the best-positioned to change it. “Either you have to get involved outside, or be a police officer and be involved inside,” said Arnold, who leads the Sentinel Police Association. "We've been here before. We've had dialogue. We need action."
