In one Facebook post, two teenage boys posed in a photo with handguns on each of their laps.

In another, a group of young men threatened to attack another man whom they believed had cooperated with detectives investigating a string of robberies.

In each case, someone beyond family and immediate friends was watching.

Those extra eyes belonged to workers trained in mediating conflicts and mentoring at-risk young people.

In the situation involving threats, workers learned that the young man who had been threatened had actually not assisted the police, so they reached out and told the men who were making the threats. In an instant the conflict was resolved.

“The kid’s life was in danger. We cleared his name,” said Felix Polanco, a program supervisor at True2Life, a group at Central Family Life Center on Staten Island. “Our job is to save lives.”
