MELISSA ALVAREZ enjoys it when police officers behave like pals.

"This officer just took a selfie with me, the other greeted us with high-fives," said the 17-year-old Frankford resident, who is also president of the Philadelphia Youth Commission. "I want to see more officers like that!"

Alvarez was one of several panelists at "Securing our Future," a meeting on community policing yesterday in City Hall organized by several groups including the Police Advisory Commission, the Philadelphia Commission on Human Relations and the mayor's office.

"It's just fun and silly," panelist Roz Talley - the selfie-snapping uniformed officer in question - told the Daily News after the event. "And it's part of who I am. I like to see people smile."

During the event, young residents and cops sat in a semicircle, answering questions from a moderator on what communities and police can do to improve relations.

Several panelists wanted officers to get out of their patrol cars, walk through their assigned neighborhoods and meet residents.

"Having positive interactions not related to law enforcement, like playing ball or jumping rope, can have a huge impact," said Lance Carter, 26, of North Philly.

"You can't get to know people in a police car going 45 miles per hour," said Everett Gillison, Mayor Nutter's chief of staff.

Chris Lai, who formerly patrolled in the 17th District that includes Point Breeze, said he gave his cellphone number to residents and made sure they knew his name.

"The most important thing is to let people know you're there," he said. "When I'm patrolling, I'm not Officer Lai, I'm Chris."

Lai, who now works in the police's Forensic Science Bureau, said that giving his cell number to residents also scored him some tips on incidents.

"I wouldn't have been a good cop without the people who helped me," Lai added.
