Mayor Bill de Blasio and the head of the city’s largest police union kept an icy distance from one another during Thursday’s inaugural address by Gov. Andrew Cuomo — who vowed to enact reforms to defuse tensions between cops and minorities.

“The world saw an African-American man in Staten Island die and people are confused, disappointed and angry,” Cuomo said, referring to the Eric Garner case.

“Law enforcement officials have been wrongfully targeted and even assassinated. The situation has devolved into one in which everyone is talking and but no one is listening. It must stop.”

He indicated Albany would take a hand in the matter, adding, “The truth is the justice system does need review.”

Cuomo said cops need more safety and protection, but “law enforcement needs to respect the community as much as the community needs to respect law enforcement.”

Both the mayor and Patrick Lynch, president of the Patrolmen’s Benevolent Association, attended the speech at 1 World Trade Center.

But they never crossed paths.

Lynch later issued a statement lauding Cuomo.

“During these difficult days, as we prepare to bury another New York City police officer cut down before the prime of his life, it is reassuring to hear the calm, practical and reasoning voice of Gov. Andrew Cuomo and his call for respect and support of law enforcement,” Lynch said.

He added: “Those who continue to call for better relations between police and the community don’t seem to understand that, in most cases, police are the community. We live, work and rear our families in the same neighborhoods that we protect.”
