Kevin Johnson, the CEO of Starbucks, called for “unconscious bias” training for store managers and apologized for what he called “reprehensible” circumstances that led to the arrest of two black men at a Philadelphia store last week. He said in an interview on “Good Morning America” that the company was reviewing the actions of the store manager who had called the police. Johnson said that “what happened to those two gentlemen was wrong.”

“My responsibility is to look not only to that individual but look more broadly at the circumstances that set that up just to ensure that never happens again,” the executive told an interviewer. He added that he wants to personally apologize to the men, saying the company “stands firmly against discrimination or racial profiling.”

Officers went to the store after receiving a report that the men were trespassing, said Police Commissioner Richard Ross. He said officers were told the men had come in and asked to use the restroom but were denied because they hadn’t bought anything. He said they then refused to leave.

The two men are real estate brokers who were going to meet up with Andrew Yaffe, who runs a real estate development firm. They were going to have a business meeting in Starbucks regarding business investment opportunities. However, they would not be able to speak. “Why would they be asked to leave?” Yaffe asked on a video. “Does anybody else think this is ridiculous? It’s absolute discrimination.”

The two men were taken out in handcuffs. They were held for nearly nine hours before being released, said Lauren Wimmer, an attorney who represented the men over the weekend. No charges were filed, authorities said. Benjamin Waxman, a spokesman for Philadelphia District Attorney Larry Krasner, said over the weekend that the office decided that there “wasn’t sufficient evidence to charge [the men] with a crime.”

Demonstrators convened at the location. One person in the crowd hoisted a sign that read, “Is she fired or nah?” This is a reference to the store manager who called police. Others chanted, “Anti-blackness anywhere is anti-blackness everywhere.”
