Contra Costa County occupies the northern portion of the East Bay region of the San Francisco Bay Area, California.  It is primarily suburban, and has a population of about 1,200,000. The county seat is Martinez. Commercial sex activity has been well-documented in the communities, and in unincorporated areas of the county. This activity and the problems and ancillary crimes it generates results in complaints to law enforcement agencies from residents and businesses. Among the more serious crimes associated with the local commercial sex market is sex trafficking, and violence committed against both the providers and consumers.

Consumer level demand provides the revenue stream for all prostitution and sex trafficking, and has therefore been targeted by local law enforcement agencies as a strategy for prevention and response. The Contra Costa Sheriff’s Department often collaborates with municipal police departments to conduct reverse stings.  For example, in Bay Point (formerly West Pittbsurg) complaints about prostitution from residents and businesses, as well as homicides involving prostituted women, encouraged the Contra Costa County Sheriff’s Office to adopt new strategies that target sex buyers in addition to sex sellers, and have conducted a street-level reverse sting operations to arrest buyers.

Pittsburg is near Bay Point, Antioch, Concord, and Walnut Creek,  and prostitution and sex trafficking have been identified as problems in those communities, including the presence of  a serial killer who targeted sex sellers in the 1990s. In their efforts to reduce prostitution, the Contra Costa County Sheriff’s Office and Pittsburg Police Department have conducted periodic reverse stings since at least 1998. Operations are typically conducted at street level, using one or more female undercover officers as decoys. The names of arrested johns are not routinely released to the public.  In 1998, media outlets reported that county officials were considering adopting an auto seizure ordinance that would enable them to seize and impound vehicles used for the purposes of solicitation. It is unclear if said ordinance was ultimately adopted.

The Richmond Police Department began conducting street-level reverse stings in 2005, and web-based reverse stings in 2008. Once arrested, johns in Richmond may have their vehicles seized (if they were used for the purposes of solicitation) and may have their driver’s licenses suspended. If convicted, they may be served with SOAP orders that restrict their ability to enter areas of the city known for prostitution. In March 2014, the RPD announced that it would also use its Facebook and Twitter pages to broadcast the identities of arrested sex buyers; in September 2014, the names and arrest photos of 11 johns were posted to the department’s Facebook page following a sting operation. In October 2018, a reverse sting on 23rd Street yielded arrests of eight customers and the rescue of two juvenile girls ages 15 and 17. Residents and city officials have also undertaken efforts to address demand prior to the point of arrest, by engaging in public education campaigns and developing neighborhood watch groups. In 2014, Richmond Police reported to members of the local media that had been working with “residents in the area of 23rd Street and lower Ohio Avenue to report the license plate of anyone they suspect is loitering for the purpose of soliciting a prostitute. The owner of the vehicle is then sent a ‘Dear John’ letter that notifies them they were seen loitering in an area known for prostitution.”

County-wide efforts are usually led by the Sheriff’s Department.  E.g., in  March 2017, a retired Oakland police captain was sentenced to jail, probation and a “john school” prostitution awareness class after he admitted to buying sex from a young woman at the center of a Bay Area police sex exploitation scandal.  A Contra Costa Superior Court judge sentenced the man to two years probation and five days in jail, and he was allowed to substitute “court watch” for jail time, meaning he can serve his sentence simply by sitting in a court audience. Additionally, he was required to pay approximately $1,200 to attend a “john school” program.  “Dozens” of current and former officers were investigated after the woman told investigators she’d had sex with officers from numerous Bay Area police agencies, including some who she said gave her inside information about upcoming prostitution stings. Further, she alleged that she’d had sex with officers while she was underage. The investigation implicated officers from Oakland, Livermore, Richmond, the Alameda and Contra Costa sheriff’s departments, and other agencies. It led to lawsuits against the cities of Oakland and Richmond. Four Richmond officers implicated in the scandal, out of 11 who were investigated, and three were fired.
