Philadelphia police commissioner Richard Ross apologizes to the two black men arrested at Starbucks after they were falsely accused of loitering and trespassing by the manager.

Ross apologized for defending the police officers who arrested Rashon Nelson and Donte Robinson, saying he “failed miserably” in his response, the Associated Press reported Thursday.

“I fully acknowledge that I played a significant role in making worse” incident surrounding Starbucks arrest. “I should have said the officers acted within the scope of the law, and not that they didn’t do anything wrong,” Ross said at a press conference.

During an appearance on ABC’s Good Morning America, Nelson and Robinson said the store manager called the police two minutes after they had arrived at the store for a business meeting. Starbucks will close its 8,000+ company-owned stores for racial bias training on May 29.
