Former police commissioner Bill Bratton reiterated Tuesday his interest in being the city's top cop again if Mayor-elect Bill de Blasio came calling.

Although pundits and crime experts say Bratton has the qualities that would make him good for a second stint, he would face a new set of challenges.

"It's a completely different world compared to 2002 or even four years ago," said City Councilman Peter Vallone, who chairs the Public Safety Committee. "The next commissioner will deal with a whole lot of political issues than ever before."

Bratton, 66, who served as the NYPD commissioner from 1994 to 1996, told reporters at a news conference that Mayor-elect de Blasio has neither contacted him about taking the police commissioner post nor has he "submitted an application," for the job.

However, Bratton, who also served as commissioner of the Boston and Los Angeles police departments, added that he would consider it if asked.

Andrew Moesel, a political consultant, said whoever gets the keys to One Police Plaza will have his hands full with issues that go beyond crime fighting.

In 2002, Ray Kelly had to deal with the threat of terrorism when he assumed office, and in 2013 the NYPD now has to navigate the political and social fallout from the department's stop-and-frisk policies, Moesel said.

"Bratton's challenge would be to continue to keep the city's streets safe and making sure the NYPD was less controversial than his predecessor," Moesel said.

A spokeswoman for de Blasio's transition team wouldn't comment on their candidates for commissioner.

Vallone, who has been a major supporter of Kelly, said he fears the extra scrutiny from the public and the recent inspector general bill, would make it hard for Bratton and other potential candidates to consider throwing their hat in the race.

"Unfortunately that bill and the other public safety laws will handcuff the next police commissioner," the councilman said.
