Court Ends Dragnet Electricity Surveillance Program in Sacramento (eff.org) 52

A California judge has shut down a decade-long surveillance program in which Sacramento's utility provider shared granular smart-meter data on 650,000 residents with police to hunt for cannabis grows. The EFF reports: The Sacramento County Superior Court ruled that the surveillance program run by the Sacramento Municipal Utility District (SMUD) and police violated a state privacy statute, which bars the disclosure of residents' electrical usage data with narrow exceptions. For more than a decade, SMUD coordinated with the Sacramento Police Department and other law enforcement agencies to sift through the granular smart meter data of residents without suspicion to find evidence of cannabis growing. EFF and its co-counsel represent three petitioners in the case: the Asian American Liberation Network, Khurshid Khoja, and Alfonso Nguyen. They argued that the program created a host of privacy harms -- including criminalizing innocent people, creating menacing encounters with law enforcement, and disproportionately harming the Asian community.

The court ruled that the challenged surveillance program was not part of any traditional law enforcement investigation. Investigations happen when police try to solve particular crimes and identify particular suspects. The dragnet that turned all 650,000 SMUD customers into suspects was not an investigation. "[T]he process of making regular requests for all customer information in numerous city zip codes, in the hopes of identifying evidence that could possibly be evidence of illegal activity, without any report or other evidence to suggest that such a crime may have occurred, is not an ongoing investigation," the court ruled, finding that SMUD violated its "obligations of confidentiality" under a data privacy statute. [...]

In creating and running the dragnet surveillance program, according to the court, SMUD and police "developed a relationship beyond that of utility provider and law enforcement." Multiple times a year, the police asked SMUD to search its entire database of 650,000 customers to identify people who used a large amount of monthly electricity and to analyze granular 1-hour electrical usage data to identify residents with certain electricity "consumption patterns." SMUD passed on more than 33,000 tips about supposedly "high" usage households to police. [...] Going forward, public utilities throughout California should understand that they cannot disclose customers' electricity data to law enforcement without any "evidence to support a suspicion" that a particular crime occurred.

    How many people did they get to harass just because they were having electricity usage, that they are paying for, which was "too high?" Some peoples' usage is going to be higher just because they work from home, enjoy their air conditioning, and maybe have a server farm or something.

      Who thought this was a good idea?

      Well, pretty sure the cops thought it was a great idea.

      Consider this additional California-flavored extra-special stupidity; it's currently legal for grown-ass adult homeowners to grow their own fucking weed in their own home. Even being caught with a massive grow is a misdemeanor.

      So they really went out of their way to annoy the shit out of taxpayers already paying through the nose for electricity. And California wonders why it was forced to charge an exit tax.

    that it took 10 years. Especially given from the article, "the court ruled, finding that SMUD violated its “obligations of confidentiality” under a data privacy statute." How hard is that to follow? Can the customers of SMUD sue them for privacy violations? Seems reasonable. And perhaps even find the upper management of SMUD be held criminally for the violation. Seems clearcut.

      We have the same exact thing with Flock ALPRs. Flock is going strong and growing. It takes time for a class of victims to be able to prove their case in court. The wheels of justice turn slowly.

        The fact that more people are not worried about Flock and Ring is truly disturbing on a whole new level.
        • Recently a municipality had lost a fight to prevent a freedom of information request for flock camera data.

          They instantly canceled the program and shut down the cameras.

          Remember that Steve Jobs would buy a brand new Mercedes every couple of months so that he didn't have to have a permanent license plate.

          The rich and powerful are very concerned about having their movements tracked.
      • I don't like FLOCK either, but that at least is in a public space. Your electric meter is NOT. Reasonable expectation of privacy. As I said, how this passed the smell test for ten years is unbelievable. The judge should have handed a bigger smackdown in the ruling. And I still say the SMUD people should be facing jail. I am assuming it is a private company like PG&E. If I start peeping into people's back yards to read their meter, would I be arrested? Me thinks so.
        • SMUD (Sacramento Municipal Utility District) isn't a private company. It is a publicly owned, not-for-profit electric utility. It is a governmental entity that is community-owned and governed by a seven-member Board of Directors. Those Directors need to be held accountable, and not replace with worse Directors, which I fear is what may happen. I live in Sac and love SMUD, as it is reliable and far less expensive than PG&E. I am sorely disappointed in hearing about this, I certainly thought better of t

          • Well they aren't teflon like trump, so I'd say toss their ass in jail. Even a government official is not immune from all prosecution. To me, this is a case that is clear, they broke the law, not a little, not a unclear one. It is as I said, no different then having the directors march into people's backyards and look at their meters.
    • Courts move at a snail's pace. Ten years is a bit on the long side of that, but it's not unheard of. People forget that the SCO vs IBM lawsuit started I. 2003 and was still going over a decade after that. After that point a lot of it was mostly just dealing with appeals, but the case was still ongoing in some form until 2021 when it was settled out of court. [slashdot.org]
    • The Electric Utility share holders are guarenteed an 11%-13% return on their capital investment. The rate varies from place to place but was set a hundred years ago when the electric grid was built. If the people of Sacramento successfully sue SMUD, the public regulator will just raise the electric rates to everyone in Sacramento, such that SMUD in the long run still makes the same profit. So in the end all that would happen is lawyers would get paid but no SMUD customers would see any releif.
    • Agreed, this is why the current admin can break the law and let the courts has it out for 10 years before stopping them. There should have been an immediate cease and desist while the court deliberated!
  • Good thing I'm not in SMUD territory. I use 2 sigma out of electricity, because I use a lot of electric heaters despite having a gas-fired furnace. I would have had some visits from the SS.

    I used to mine Ethereum in my garage with nearly 200 GPUs. My electricity base load was about 13kW. After a couple of weeks, I came home from work to a gaggle of police, SWAT, DEA, and FBI agents ransacking my house and violently ripping computer hardware out of my garage.

    A judge had given them a search warrant to seize "marijuana growing equipment" from my house without having any proof at all that I was growing MJ. The cops decided that racks of open-frame GPU miners were "growing equipment" and basically destroyed $50K worth of mining equipment during the confiscation and did $75K worth of damage to the house.

    I sued, and a State Appellate Court Judge ruled that it was "reasonable" for the police to think that racks of computer equipment were part of a growing operation, and that they were not liable for the damage, and that I was not entitled to get my property back. I had already spent $100K on the lawsuit by that point and just didn't have any money left to appeal to the State Supreme Court.

    All in all this absurdity cost me nearly half a million dollars between destroyed equipment, damaged home, lawyer fees, and lost mining revenue.

    It has been 8 years since it all went down and I've never been able to get any kind of acknowledgement at all that this was a mistake. Just like "oh well too bad"

    Just imagine the cost of this over the course of a decade. The utility seems to have borne the brunt of the work, having to analyze and filter this data multiple times per year. That cost would have been passed onto customers - I'm sure it's appreciated that everyone's power bill was just a bit higher to fund this fishing expedition by law enforcement.

    Then of course the investigators would be tied up digging through the 33,000 "tips" this data produced. Literally, law enforcement had to review 33,000 potential customers who met this profile, checking them for warrants or other known crimes giving them some excuse to surveil or even search that residence. Pretty extreme when you think about it - and that is just to catch people growing weed of all things. Not the dangerous drugs killing people or contributing to the homeless population on so on.

    Finally, the fact that this generated so many potential leads shows how stupid the concept is in general - the "profile" they were going after regarding power usage. I can think of a hundred of other things that would cause higher power usage 24/7 that has nothing to do with growing weed.

  • The readings are downloaded frequently and have a granularity of less than a day. So if your electricity usage suddenly drops this can be noticed.

    All it takes is a sysadmin type under financial pressure (divorce, gambling debts, medical bills, ...) who needs cash. S/he will be prey to crooks who can get them to do some SQL queries, or similar, to identify usage drops and pass them to the crooks - these addresses are prolly empty as the inhabitant may be away on holiday -- a great place to send a burglar.

  • disproportionately harming the Asian community.

    I wasn't aware that cannabis use (drugs in particular) were a serious problem in the Asian comunity. Particularly due to the exploitation of the Chinese by the British opium trade in the 19th century, most of the people of Asian descent that I associate with steer clear of the "white man's drugs".

      disproportionately harming the Asian community.

      Yeah, I'm not getting this either. That's a lot of rice cookers going ever day to spike the usage that much.

    • Looking into the sources and tracing a bit:

      The city has assessed the vast majority of the fines—more than 85 percent—against owners of Asian descent. A SMUD analyst avoided searching homes in a predominantly white neighborhood, while a police official removed non-Asian names from one of the lists generated by SMUD before forwarding the information on for further investigation.

      source [eff.org].

      If they actually did this, well, that's like how the NRA forced most "may issue" states to be effectively "shall issue" for various weapon permits.

      When the police can't come up with a good reason for denying the black woman's permit request when she has letters from a ex-boyfriend stalker threatening to kill her, who is due to be released from prison soon, but the white doctor living in a gated community gets it first thing, there are questions to be asked.

    • As I recall, there has been an issue with Chinese nationals running illegal grow operations in the US. If that was what they were looking for, it would naturally impact "Asians" disproportionately. Chinese gangsters are Chinese after all.

    During my power company career a few decades ago, this was a real thing. But that was due to the use of power-hungry HID lamps. Today, it's mainly LED lamps, which consume much less power. Small grow operations consumption data drops down into the noise level of typical home use.

    Large grows can be found by walking drug dogs through your neighborhood. Or drones equiped with chemical sensors.

    I was working for a large grower, and (legally) growing with 6 lights myself in an ADU (Accessory Dwelling Unit) on my property. My boss got a letter in the mail while my coworkers and I were trimming flower, and everybody disappeared within the hour, except for a guy who lived there. I had shut down my grow a few months before for two reasons: the law was going to change that summer, and I caught the city going through my trash cans one morning. Never seen anything like that before, or since, and that was enough to scare me off. So regardless of legality/morality, it was certainly an effective strategy.
  • Every complaint about a fruitless investigation carries weight. When reasonable suspicion reveals a dragnet thats is a waste of taxpayer dollars, lazy police work, and a program that does not benefit the community it has to be ended. Its clear that using erroneous info to create a disruption in everyday lives and people will only take so much. This program has been made public many years ago so anyone serious enough to start a grow would have figured out a work around. Because of the law enforcement over-re

    "You're using electricity suspiciously! Where are the drugs?"
  • Wasn't there a story from the late '80s or maybe the late '90s where some guy got a visit by the cops after the electric company reported unusually high electrical usage from one of their customers, and it turned out the guy wasn't growing anything but was just running a VAX?
