The San Francisco Police Department’s latest effort to “crack down on prostitution” in the Mission invites the public to send in photos of the license plates of people suspected of soliciting sex.
Some community members, however, say the initiative has prompted more questions than answers.
In August, the city installed cameras along Shotwell Street in response to a lawsuit from a group of neighbors over what they called San Francisco’s inability to address sex work and vagrancy on their street.
Now, through the “Dear John” program launched last week, police will also collect images submitted by the public via an online portal. The license plates identified in these photos and videos will then be traced back to an address.
“SFPD has begun sending letters, and pictures, to the addresses of registered vehicles seen and captured on camera soliciting prostitution along Shotwell and surrounding streets,” the department announced last Wednesday.
More than 30 letters have been sent in the last two weeks, said Evan Sernoffsky, the police department’s director of strategic communications.
The letters, designed to embarrass people and erase anonymity, inform the recipient that their vehicle “was observed in an area” with “high rates of prostitution” and remind them that engaging in or soliciting prostitution is “not a victimless crime.”
Deterring sex work does not appear to be an exact science: “If this notice was sent in error,” a sample letter concludes, “please disregard it.”
This ambiguity has raised some concerns for community members.
Ayman Farahat, a data scientist and the lead plaintiff of the Shotwell neighbors’ lawsuit, said he can’t cast judgment until he sees data that would allow him to quantitatively evaluate the “Dear John” program.
Sernoffsky noted that problem. “Crime is fickle,” he said. “It’s challenging to measure.”
As such, crime metrics are sometimes measured anecdotally, Sernoffsky continued: “If fewer people are soliciting prostitution, we will consider that the right direction.”
A specific indication of success, Sernoffsky said, is if a car police used to regularly see soliciting sex disappears after a letter is sent.
“But, in general, we don’t have somebody out there with a clipboard or one of those counter things — like when you go into the ballpark — measuring the number of prostitutes.”
There are currently “no expectations” of how many photographs will be sent in, he said.

Neighborhood critics — like those who were against similar “Dear John” programs in Oakland, San Jose, and Los Angeles — have also raised privacy concerns about the letters and street surveillance.
Sernoffsky, however, said SFPD had no plans to release the photographs it collected, and didn’t anticipate its letters becoming public record. Recipients, after all, would not be charged with a crime.
Mission resident John Bove said he was “happy with any effort to curb the activity” that involved “going after Johns, not the sex workers.” Still, he worried that the “Dear John” program would put “all the onus on citizens.”
People are cautioned against putting themselves at risk to capture photographs, Sernoffsky said. SFPD’s portal, the spokesperson added, is meant to be just “one more tool in our tool belt” to combat sex trafficking.
Though SFPD lacks the resources to monitor prostitution at all hours, Sernoffsky said they will also continue to leverage new mobile-security units, traditional neighborhood patrols, and barricades like the ones on Capp Street to deter those soliciting sex.
Nonetheless, Shotwell community member and San Francisco State University public policy lecturer Bob Allen remains pessimistic about the city’s efforts.
Allen said he felt the sex work problem would continue to be “shuffled around” the neighborhood by initiatives that create an illusion that something is being done, but in reality present no measurable solution.
But “data, information, and evidence matter less than the perception of the public,” he sighed.


This plan is pathetic. Innocent until proven guilty.
How would the police like it if they received a letter saying ya know we don’t have evidence of you beating civilians but we have photos of you leaving an event where civilians were beaten by the police, MAKE OF IT WHAT YOU WILL
Imagine someone’s marriage ends because of this? I’d sue the police.
I was raised on Shotwell and lived there from 1964 to 2009. Every time I hear news of something happening on Shotwell my heart skips a beat with fond memories. But SFPD is trying to make me laugh to death with this plan.
Ahh anonymously calling the police on someone: It’s the stuff of totalitarian regimes. Who said SF was progressive?
I’ve anonymously called the police on someone trying to break into my apartment. I guess that makes me a totalitarian in your world view.
Can MissionLocal do a test ?
Maybe drive around and talk to the hookers? Maybe ask a question to engage conversation ? Ask for feedback about the new mayor. Just talk to them for a couple minutes . Nothing sexual . No need to touch breast or anything . Don’t show genitals or anything . See if a letter comes in mail .
No
This is a violation of privacy. It’s also accusing people of a crime without any evidence whatsoever.
I can’t believe SFPD, which doesn’t have enough officers to do traffic stops, has the manpower to do this.
SFPD officers are not sociologists or social workers. They are not psychologists or psychiatrists or pharmacologists. They are not anthropologists. SFPD’s mantra is that they are understaffed. Focusing the scant number of officers on community safety from gangs and gun violence, from robbers, burglars, home invasions and street assaults is critical. SFPD’s charging and clearance rates for violent crime (robbery, aggravated, assault, burglaries) and vehicle and larceny theft are all below state and national averages. Maybe SFPD should spend less time behind desks and more time patrolling our sidewalks and streets. This “Dear John” strategy is feeble minded.
Wow, what can go wrong?
Don’t like a neighbor send a pix.
Have a coworker you don’t like send a close up pix of the license plate.
It’s a crime to lie to police. It’s also civilly actionable, if caught. Big mistake.
They don’t have these problems in Amsterdam where prostitution is legal. There are entire countries where it’s legal and they have less problems.
Why not just create a sex worker zone, say in Golden Gate park? I used to have lots of sex there in my younger days between the two wind mills. Now it’s been co opted by the soccer players, but what gives them the right to have a place set aside for their soccer playing and not a place for sex aficionados too? People who have sex, pay taxes too, where are their city funded amenities?
SFPD is run by AI now. Chinatown, Jake.
Campers,
Let’s have the best Legal Sex in the World …
Seriously
If anyone in the World can get this right, it’s San Francisco.
Face it, we need a new industry or two or three that are Renewable and 8 billion of us walking around and keeping on doing it proves Sex is Renewable.
Take that mess down on Capp Street and turn it over to some group like, off the top of my head, the Sisters of Perpetual Indulgence and partner them with, oh …
The San Francisco Department of Public Health which is as good as you’re going to get in the World public type and if you need more expertise we have plenty of Nobels floating around at Bay Area hospitals.
We can control the health side.
Structure ?
I’m thinking you start with a BOS Committee before this Board is done chaired by Aaron Peskin (here’s your real legacy, boy) …
Explore issuing Free Permits to applicants who pass a Health Screen.
Brothel Licenses …
Now, that one there, that’s where the Gold Mine is like when the First Pot Clubs opened and they’ll have continued competition from Criminal Interests but Legal Sex is not really what we’re talking about here is it ?
Nope, we’re talking about Full Hotels and Restaurants and Robo Taxis and on and on.
We can use the Trade to Compliment our new Ohlone Indian Casino Lurie put in at the old Armory on Mission Street that h. brown can see from his East window …
Go Niners !!
