"Messaging is important and I failed miserably in this regard," Ross said.
Despite that admission, Ross defended the actions of his officers when theyat a Starbucks last week. The incident was captured on cellphone video and posted online.
"It is important to emphasize and underscore that these officers had legal standing to make this arrest," Ross said over the weekend. "These officers did absolutely nothing wrong."
But Thursday, he took the blame for making what he said was a bad situation worse.
"I can appreciate in light of the Starbucks policy and how well know it is to many, why these two men were appalled when they were asked to leave. For this reason, me, I apologize," Ross said.
His remarks came hours after the two men,, told ABC their story.
"As soon as they approached us they just say we have to leave," Nelson said. "There was no question of you, you know, was there a problem here with you and the manager."
"At the time we wasn't [sic] read any rights, nothing," Robinson said. "Just double-locked in handcuffs behind our back and escorted out to the squad car."
Starbucks has apologized to the men and will be training all of its employees on how to. Lorie Friedell trains police on the subject.

Nelson and Robinson said they want change after what they went through and believe Starbucks' plan to shut down its stores in May for racial sensitivity training is a good start.
