NEW YORK, NY - APRIL 14:  Thousands of police officers and firefighters stand at attention as the coffin of fallen New York Police Department (NYPD) officer Dennis Guerra is brought out of St. Rose of Lima Church in Far Rockaway, Queens on April 14, 2014 in New York City. Guerra died last week from injuries suffered in an arson blaze at a Coney Island public housing apartment building. Guerra's patrol partner, Rosa Rodriguez, remains in critical condition. Felony murder charges were brought against Marcell Dockery, 16, who confessed that he set a mattress on fire because he was bored. (Photo by Spencer Platt/Getty Images)
