Congressman Charles Rangel, in a snide aside Saturday, suggested even President Obama was at risk on the streets after a black cop was slain by a white colleague.
The veteran Democratic politician was asked what advice he would offer Obama for the president's Saturday night visit to the city.
"Make certain he doesn't run around in East Harlem unidentified," Rangel shot back while leaving a public appearance.
Rangel's crack came as protesters marched in the streets and after Mayor Bloomberg and police union head Pat Lynch paid condolence calls to the family of Omar Edwards at their Brooklyn home.
"We lost one of New York's finest," Bloomberg said later. "... This is a loss not for just their family, obviously, which is the most tragic part, but it's a loss for the NYPD."
The mayor spent about 20 minutes with the Edwards family Saturday morning. The newlywed cop left behind a wife and two young children after he was gunned down in a case of mistaken identity.
Bloomberg had previously met with the slain officer's widow shortly after the fatal shooting. Edwards, 25, was a two-year veteran of the police force.
Lynch said the family was devastated by the loss.
"I don't think the pain ever goes away," Lynch said. "You're not supposed to bury a son. You're not supposed to bury a young father."
The mayoral visit came as the Rev. Al Sharpton, state Sen. Eric Adams and other community leaders led a vigil and rally over the shooting.
Sharpton reiterated his call for a federal investigation to determine if race was a factor in the shooting on a rainy night along 125th St.
"There's too many questions that need independent, objective answers," Sharpton told a crowd of about 250 people.
"No justice, no peace!" the crowd chanted.
Edwards was shot three times as he ran along the street, gun in hand, chasing a suspect who had broken into the officer's car, police said.
Authorities said Officer Andrew Dunton identified himself as a police officer before firing the fatal shots.
