Maybe if the parents did a better job of raising their kids, they wouldn't have wound up in these shelters in the first place! I know it's not as easy as it sounds, but the blame has to start somewhere. If the kids wind up in shelters and others under the control of gangs, something must have gone wrong prior to this.
As for prostitution and LE, prostitution has been among us for over two thousand years, probably more. And it will likely be around hundreds and thousands of years from now (unless Americans make the mistake of electing that fool Trump). The same discussion about prostitution and LE comes up every single year at around this time. A remember a few years ago, Photo Police (local tabloid based on local crime) had on its front page a picture of a couple of streetwalkers with a checkered flag and the headline "La Course aux Putes: Ca debute!!!" The article talked about the same b.s. and even named several popular agencies at the time which were prominent on the web....merb was even mentioned....and it probably treated every male person who came for GP weekend like a pervert.
The local government has bigger problems to deal with. Of course they'll say the politically correct things to appease the feminist groups causing all the brouhaha, but they've been there before and were laughed out of court....especially after the two cops (1 male, 1 female) who went undercover admitted under oath in court that they also had participated in group sex activities (while undercover!) in various clubs (e.g. L'Orage, etc) who organized such events. It destroyed any credibility they had and the prosecutors were blamed for wasting tax payers' money.
And how can they be expected to legitimately police this when some of their own also occasionally see escorts?? Years ago, one of my favorites at the time had seen this john a few times. The last time she saw him, he asked her if she was working the following day. When she said she may, he got serious and told her "please don't work tomorrow." When she asked him why, he repeated "please don't work tomorrow". She found his comment odd and decided not to work. The next thing you know, the agency got busted by LE on the day she didn't go to work. Years later, she regarded her client cop as a guardian angel. Had she not ever met him, her life may have took a turn for the worse.
