@cgarison There's a good chance those teens ran away from home and turned to prostitution to support themselves. There's even a good chance no pimps were involved at all, and they were lying about their age.
I used to know a forensic nurse who frequently worked with teens in exactly those circumstances. It's very, very, politically incorrect that there are no easy villains in most of these cases, and the best prevention would probably be funding anti-homelessness efforts.
@pete First, the majority of anti-homeless efforts fail because those programs do not have the "buy-in" from the majority of people who they are designed to support. @adam has worked with the people at Mobile Loaves and Fishes and presented their stories and I will say that it takes a great deal of patience and prayer to find the handful of homeless people that want to be part of a community and "lifted up" from their circumstance. Money alone breeds failure in these programs.
