A mentoring program in Dallas is working to close the gap between kids and those who serve.

It's called Bigs in Blue. It is part of the Big Brothers Big Sisters program. The goal is to replace distrust with friendship.

It pairs littles like 7-year-old Nyla with police officers like Christy Chamberlain, who is an officer with the Dallas police gang unit.

“We see kids they're so young and they're involved in really violent crimes. And it’s just they need mentors,” Chamberlain told NBC Nightly News. “They need someone.”

Texas police departments took a challenge earlier this year to see who could sign up the most bigs.

Since then, participation in the program has more than tripled.
