NYC Mayor Booed at Police Graduation Ceremony

New York's Mayor Bill de Blasio was greeted with boos and catcalls at a graduation ceremony for new police officers today where he told the cadets they can be "part of the solution."

The rude greeting came just days after police officers turned their backs on the mayor at the funeral of a slain officer.

The mayor's comments were the first to police since this weekend when hundreds of officers turned their backs on an outdoor monitor showing de Blasio speaking at the funeral of Officer Rafael Ramos. Ramos and Officer Wenjian Liu were ambushed in Brooklyn Dec. 20 while sitting in their squad car. The gunman later killed himself. Liu's funeral will be held next weekend.

De Blasio presided over the graduation of the nearly 900 cadets at a ceremony in Madison Square Garden. Boos and catcalls cascaded down upon the mayor when he was introduced. There was a smattering of polite applause.

At one point de Blasio said "you didn't create problems," and someone in the crowd shouted audibly "No, you did!" The recruits were stoic.

The mayor continued, telling the cadets, "You can be part of the solution and that is a blessing." He quoted from the Bible saying, "Blessed are the peacemakers for they shall be children of God... We lost two peacemakers... They were children of God for sure."
