Child sex workers are usually forced into it either through homelessness or through coercion. What has been happening is the children were rescued from their pimps... just to be charged with prostitution. So they get a double whammy of being sexually abused AND having a criminal record for sex work. Rather than find these kids a good home and therapy, they are put into jail cells and turned into institutionalized criminals. The new changes lets the child off, but not the John. The John still gets busted for raping a child.
