NEW YORK (Reuters) - New York Mayor Bill de Blasio faced the biggest crisis of his political career on Sunday after a gunman killed two police officers in an attack intended to avenge recent police killings of unarmed black men in the United States.
New York police officers turned their backs on de Blasio in protest during a news conference and their union said the mayor had blood on his hands after Saturday's shooting. Police investigators have said the killings were the work of a 28-year-old black man with a long arrest record who may have had past mental troubles and who warned of his intentions on social media.
