I suggest that a better alternative to simply citing and releasing those arrested for soliciting sex would be to require them to attend sex traffic school. They could then be educated about the risks entailed both to themselves and their partners and about the damage suffered by women working as prostitutes.
While it might not be possible to duplicate the variety of programs and themes offered by conventional traffic schools, the money could be used to fund womens programs, particularly those that help rehabilitate women involved in prostitution. Im sure that the gender studies department at Cal Poly would be well-suited to develop a sex traffic awareness school and that it would be quite helpful.
Simply put, send the Johns back to the classroom.
