A Black Florida doctor who has been testing homeless people for COVID-19 was stopped outside his home and handcuffed Friday for—get this—unloading old boxes from his van for curbside pickup, he told the Miami Herald. Dr. Armen Henderson, who was earlier featured in the Herald for his heroic work to fight the spread of the novel coronavirus, told the newspaper that by the cop’s account, police had been getting complaints of people illegally dumping garbage in a Miami neighborhood. So a sergeant patrolling the area stopped Henderson and asked him for his identification, and when he didn’t provide it and turned to his van, the cop handcuffed him, Henderson told the Herald.

“He said ‘you should refer to me as sir, or sergeant when talking to me,’” Henderson told the Herald. “I never said I was a doctor. But I didn’t cuss. He just grabbed my arms and cuffed me.”
