Reuters, New York :Protesters in New York and other cities rallied for a third night on Friday denouncing the use of deadly force by police against minorities, even as prosecutors said they would consider charges against an officer in the fatal shooting of a unarmed black man in November.The slaying of Akai Gurley, 28, gunned down in a dimly lit stairwell in the New York borough of Brooklyn, was the latest in a string of lethal police actions feeding U.S. public outrage over what many perceive as racially based violence by law enforcement.This week’s wave of angry but largely peaceful protests began Wednesday when a New York grand jury declined to bring charges against white officer Daniel Pantaleo in the chokehold death of Eric Garner, a black 43-year-old father of six. Garner, who had no weapon, was being arrested on suspicion of selling cigarettes illegally. A videotape of his confrontation with police on Staten Island in July showed Pantaleo’s arm across Garner’s neck as he is subdued by four officers, then Garner was pinned face down to the pavement as he repeatedly gasps, “I can’t breathe” – a phrase protesters have adopted as a rallying cry.The decision sparing Pantaleo from prosecution was announced nine days after a Missouri grand jury chose not to indict a white policeman for the shooting death in August of an unarmed black teenager in the St. Louis suburb of Ferguson, spurring two nights of arson and unrest there.Then on Thursday in Phoenix, Arizona, another unarmed black man was shot dead by a white police officer during a scuffle, leading to protests in that city.
