December 1, 2005 -- The hero cop cut down by a cold-blooded criminal during a traffic stop was promoted posthumously to detective first grade yesterday.

"Dillon Stewart, though wounded, helped bring his killer to ground, demonstrating remarkable courage and tenacity," Police Commissioner Ray Kelly said at the ceremony.

Meanwhile, sources told The Post alleged killer Allan Cameron has been indicted for the murder as well as attempted murder in an earlier cop shooting.

The promotion effectively means a $21,200 bump in the late officer's salary — and ensures that his widow, Leslyn, will receive an estimated $80,000 annual pension, sources said.

Kelly called the promotion "a small measure of the enduring gratitude that 8 million New Yorkers feel for everything Officer Dillon Stewart did to serve and protect us."

Stewart was slain early Monday as he and his partner, Paul Lipka — who were both in uniform — pulled over a motorist on a traffic violation.

Cameron, 27, allegedly fired at the officers several times, hitting Stewart under his arm — above his protective vest.

One bullet cut through Stewart's heart — but, seemingly unaware of his mortal injury, he and his partner kept up their pursuit of Cameron.

"We've got to stop this craziness," said Mayor Bloomberg yesterday.

"I don't know how many people have to die or how many police officers have to die before we realize that the right to bear arms is one thing, and people walking around with guns under their coats, even teenagers, is just insanity."

Meanwhile, officials pressed their complaints yesterday that Philadelphia authorities stumbled in 2003 when they charged Cameron with resisting arrest and assaulting a cop.

Cameron — also accused in the Nov. 19 shooting of Brooklyn officer Wiener Philippe — was charged in Philly in March 2003 with assaulting an officer.

Cameron skipped court in the Philly case, which could have gotten him a 10-year prison stretch.

In December 2003, he appeared in a Brooklyn court on a traffic rap.

New York officials say they would have held Cameron on the Philadelphia charge if they'd known of it. Instead, the Brooklyn judge released Cameron.

Philly authorities said they notified the NYPD of the charges by fax more than a week before the Brooklyn hearing.

But Kelly said Philadelphia officials should have put the info in the National Criminal Information Center database.

Among those paying their respects to Stewart's colleagues at the 70th Precinct yesterday was the Rev. Al Sharpton, who recalled that station house was where Abner Louima was sodomized in 1997 by an officer.

"We should be just as vocal when policemen are victims as we are when we feel they are perpetrators of crime," he said.
