A "soliciting prostitution" sting operation is an operation routinely run by local law enforcement to arrest "Johns". This operation is used by nearly every local law enforcement agency other than the California Highway Patrol. Oceanside Police, Escondido Police and Carlsbad Police seem to use it more than other departments and the way they run it may differ. They offer an "opportunity" to solicit sex for money by individuals, usually males and referred to as "Johns". The crime is the "asking for sex in return for payment" whether or not it is performed or not is irrelevant. There are possible entrapment issues, but the police try to be careful to avoid those issues. Additionally, most people do not want to go to trial, even if they have a good case, because of the embarassment, fear their family, spouse, girlfriend or employer will find out. Fortunately an experienced criminal defense attorney can play an important role in trying to get the charges dismissed if there are defensible issues, or reduced to lesser unrelated charges like "disturbing the peace".
