The people that buy their services are still breaking the law...
So the children get taken off the street and given help and treatment instead of being put in jail, and this is bad?
Exactly where do you see any mention of being taken off the street and receiving treatment mentioned?
From the laws own wording...
"A commercially exploited child under this paragraph may be adjudged a dependent child of the court pursuant to paragraph (2) of subdivision (b) of Section 300 of the Welfare and Institutions Code and may be taken into temporary custody pursuant to subdivision (a) of Section 305 of the Welfare and Institutions Code, if the conditions allowing temporary custody without warrant are met."
It's sounds to me like they MAY be temporarily taken off the street. And if past experience is worth anything, I'm certain they will find a way to make sure they are released asap. I see no mention of treatment. Face it these children will be back on the street quicker than before.
