I work with teens in the sex trade and it's definitely true that "rescues" are not helpful at all. I wrote about it in my blog too. http://www.rethinkresources.net/2008/06/25/ap-reports-345-arrested-kids-..., and http://www.rethinkresources.net/2008/06/26/local-reports-from-the-arrest...

I'll point out too that at least 290 of the arrests were of adult women (18 and over) who were charged with offering sex for money, and may possibly face federal charges if the feds believe they had any involvement with minors in the sex trade. They also arrested people offering money for sex in that number. Very few were charged with pimping offenses at all.
