San Mateo County pumped $12 million into a grand AI surveillance system made by billionaire Tom Siebel’s C3 AI that was supposed to level up its police work. Three years into the project, cops say they still haven’t seen the benefits.

00:00Today on Forbes, this billionaire's AI was supposed to speed up policing. It's not going well.
00:07In June 2022 in California, the San Mateo County Sheriff's Office organized what they called a
00:14quote, day of fun, down at the Coyote Point shooting range. The department's IT team and
00:20staff from C3AI, a $2.4 billion market cap company founded by billionaire Tom Siebel,
00:27were invited to celebrate their work on a new surveillance system intended to unify
00:31police data from agencies across the county into a single app. After lunch, C3AI staff could
00:38practice shooting targets at the same facility where the cops trained. The choice of venue was
00:43not accidental. In 2018, Siebel's foundation gave $4.5 million to the county to fund the range's
00:51refurbishment. Working closely with C3AI and its longtime partner, Amazon Web Services,
00:57the Sheriff's Office wanted to connect masses of data from at least 15 different agencies under
01:02its jurisdiction, collected from devices like license plate readers, surveillance cameras,
01:08arrest records, 911 calls, and historical police databases. At the core of Project Sherlock,
01:15named for Arthur Conan Doyle's fictional detective, was artificial intelligence that could piece the
01:20data together, find leads for investigators, and give situational awareness to cops on the beat.
01:26The ultimate aim was to dramatically speed up the grunt work of policing.
01:30For C3AI, Sherlock was set to be a flagship contract for the company's local government division.
01:37And so crucial was it that Siebel himself was deeply involved in the early stages of the work,
01:42down to writing sections of the contract and hosting San Mateo cops at his offices in Redwood City.
01:47But $12 million and three years later, Project Sherlock has struggled with usability issues,
01:54feature oversights, and significant delays, in some cases well over a year,
01:59according to public records obtained by Forbes. A timeline of the planned Sherlock rollout,
02:05obtained via public records, showed that 14 agencies were due to go live with Sherlock by January this
02:10year at the latest. Seven of those agencies, Atherton, Belmont, East Palo Alto, Foster City,
02:18Menlo Park, San Bruno, and South San Francisco, told Forbes that they didn't have access to a fully
02:23functional product and therefore hadn't seen any investigational benefit. The San Mateo County Sheriff's
02:30Office claimed that in fact the Foster City and San Bruno Police Departments did have access,
02:34along with Daly City, Redwood City, and San Mateo. The agency didn't clarify, however,
02:41whether officers at onboarded agencies were actively using Sherlock or if they were like
02:46Foster City, which was due to go live as of May 31st last year, but, per Chief Corey Call,
02:52was, quote, not seeing any benefits yet as this project is still in the developmental stages.
02:58Similarly, San Bruno's former interim chief, Susan Manheimer, told Forbes in June,
03:03the department was using a limited beta version of Sherlock.
03:07Menlo Park Police Department Chief David Norris said all 14 agencies were, quote,
03:12behind the implementation schedule in the timeline. Norris said, quote,
03:17while the technology itself is onboarded, the practical implementation has been delayed.
03:23Belmont Lieutenant Clyde Hussey, his department's project manager for Sherlock,
03:28confirmed the delays, adding that he was unable to explain them. He said, quote,
03:33I wish I had a good answer for you. After this story was first published last week,
03:38Hussey said some select staff were recently given access.
03:42The other agencies didn't respond to requests for comment.
03:46The stuttering progress of Project Sherlock, the name and nature of which has been reported by
03:51Forbes for the first time, shows how even with the backing of a Silicon Valley billionaire in Siebel,
03:56and one of the world's most powerful companies in Amazon,
04:00AI's much-hyped use in policing is running into bureaucratic stumbling blocks
04:04and problems performing as promised.
04:06In San Mateo County, the hope that AI plus mass collection of surveillance data
04:11would get vital information into the hands of cops faster has yet to be fully realized.
