NEW YORK — Leaders of the city’s Black Lives Matter movement on Wednesday threatened “riots” and “bloodshed” in the streets if Mayor-elect Eric Adams reverses the abolition of the NYPD’s controversial anti-crime units. “If he thinks that they’re going to go back to the old ways of policing, then we are going to take to the streets again. There will be riots, there will be fire and there will be bloodshed because we believe in defending our people,” said Hawk Newsome, co-founder of Black Lives Matter of Greater New York, after a heated meeting with Adams in Brooklyn Borough Hall.
