Gov. Andrew Cuomo injected himself into the roiling debate over the wrongful police death of Eric Garner on Wednesday by attacking Mayor Bill de Blasio for taking five years to bring administrative charges against the cop involved, Officer Daniel Pantaleo.

“This is an issue that should have been handled by the New York authorities much earlier on,” Cuomo told reporters at an unrelated press conference in Lower Manhattan. “How do you say no one did anything wrong, and no one is disciplined and no one is punished, but Eric Garner is gone.”

He added: “But the best course for the city and for the NYPD is when and if someone does something wrong, you know what you say? The person did something wrong. That actually increases the credibility of the city and the police department.”

But, Cuomo refused to take a stand on if Pantaleo should keep his job — and instead echoed an answer frequently provided by de Blasio, who also refuses to comment on the cop’s future.

“That’s a decision for the NYPD and New York City,” the longtime pol said. “But I believe the facts should be reviewed and justice should be done and it shouldn’t be political.”

Asked about Cuomo’s criticism, the de Blasio administration again tried to pin the years-long delay in bringing administrative charges against Pantaleo on the feds.

“What happened to Eric Garner is a tragedy. The fact that the Garner family has waited five years is unspeakable,” said de Blasio press secretary Freddi Goldstein. “We should never have put our faith in the federal government and we’ll never make that mistake again.”

She added: “The City’s disciplinary process is underway and a decision is expected by August 31.”

Protesters took to the streets again near City Hall on Wednesday afternoon, condemning the US Justice Department’s decision Tuesday to not bring civil rights charges against Pantaleo and de Blasio’s refusal to demand the officer’s firing.
