Does the Big Brothers Program Help Reduce Crime in the City?

Mayoral candidate Dwight Evans thinks so:
Dwight Evans held a press conference on Thursday, April 12th to announce his pledge to fully support Big Brothers/Big Sisters of Philadelphia and their mentor programs as a way to reduce violence in the city. As a show of his commitment to Big Brothers/Big Sisters, Dwight signed up to be a Big Brother for a young child in Philadelphia.
“I fundamentally believe that we can overcome this scourge of violence Philadelphia is suffering through right now,” Evans said. “Community involvement and personal commitment will be keys to ending the violence, and Big Brothers/Big Sisters is a model combination of both these elements.
