A New York Police Department officer was stripped of his gun and badge as Mayor Bill de Blasio and Police Commissioner William J. Bratton issued swift apologies on Thursday for the rough arrest of James Blake, the retired tennis star, after he was misidentified as a suspect in a fraudulent credit card ring.
Criticism swirled over the possibility that Mr. Blake, who is biracial, had been racially profiled in the episode on Wednesday. But it was Mr. Bratton’s acknowledgment that Mr. Blake may have been treated too aggressively when an officer threw him to the ground that put a renewed focus on the everyday arrest tactics long criticized by the city’s minority residents.
