Can I submit a FOIA request to get all the plate reads from Flock for my town's mayor or police chief (their private vehicles) so that I can create a map of where they go and share it online? I genuinely don't know the answer as I've not tried, but from things I've read I'm pretty sure they will not provide this. And that's the point - why can a police officer search the database for any plate they feel like but the…

They will generally deny you access, but they will access it freely themselves despite this being data collected on public streets. That’s the disparity at issue. However there’s no law from you putting up your own camera, pointing it at a public street and publishing the details of every car that drives past and highlighting any interesting once’s, like the mayor, police chief, etc. I suspect when there’s been a few…

Yes, and I keep thinking an organized, crowd-sourced effort like people do for capturing ADSB data or weather stations would be tempting. Setting up the hardware would be a little more involved though (mostly because of needing to locate it near the street). Cost is probably not even much worse than an ADSB monitor now.

Something like this is probably inevitable, either as a grassroots effort or via something like Amazon's Ring network. Short term it could prompt officials into action, but I fear long term it would be bad for society - laws might be written to prohibit it, but those would have side effects of limiting other things (like the aforementioned ADSB monitoring network).

Great, now rigidly define scale...

SCOTUS has (sort of) done this in the recent Chatrie case. https://www.supremecourt.gov/opinions/25pdf/25-112_0am4.pdf It's obviously different in that Chatrie was about google location data, and there actually was a warrant. SCOTUS ruled that warrant was too broad since it captured everyone in that location, not a specific person(s). Constitutional scholars have pointed out the ALPR are next in line to face challeng…

OK sure, but do they now also need a warrant to look at their own footage from their body cam, or their dashcam? What about the camera on the side of the municipal building?

Compelling parties to give up data is different than looking at your own data. And it is firmly established that recording and reviewing footage in public space is totally fine.

So we are back to square one...How do we define scale such that a police camera on a police car is OK, but a police camera on every corner is not. Or that individuals can record in public but police cannot.

I don't understand why a police cruiser can sit in a public space (or even a private one) and write down licence plates and descriptions of passers-by with pen and paper, or record everything around them with dashcams and bodycams for later use, but when it comes to cameras on a pole this would require a warrant. Going back through police officers' notes or cruiser dash cam videos and tracking a car's movements by it…

If the police stationed officers constantly at major intersections doing that, the outcry would be no less than having cameras do it. Also, if it's the police, at least they're part of the community and people can monitor and have an effect on what they do. When it's a private company, none of that is true.

> If the police stationed officers constantly at major intersections doing that, the outcry would be no less than having cameras do it.

No.

A police officer is an expensive asset that requires a lot of investment of both time and money to create. [0] When a police department chooses to put cops on a corner doing surveillance, they're choosing to prefer that activity to any other thing that that cop could be doing. In all but the smallest towns out there, it's certain that the PD doesn't have enough officers on staff to surveil every single street corner in town. In most towns, it's prohibitively expensive (in terms of training cost, opportunity cost, and salaries) to set up a dragnet surveillance when one only uses humans to do the surveillance.

In contrast, cameras are far cheaper to acquire, deploy, and maintain than cops. You also only need a handful of cops to run such a surveillance system, rather than one on every corner. With cameras owned by the police or town, it's totally feasible to set up a dragnet surveillance system in most towns.

As many folks have said in the discussion about this, scale and expense are very important considerations. As few people have said, laws, regulations, and punishments that make sense when you will catch one rulebreaker in a hundred thousand often do not make sense when you will catch one rulebreaker in two. And the sorts of regulations that provide adequate restraint to police and prosecutors from interfering in people peaceably going about their lives are not the same in a society where one has to send out police to ask people face-to-face for information about someone's whereabouts as they are when police can sit at their desk in HQ and pull up complete records of 90% of that person's daily activity with five minutes of keyboard work. [1]

[0] I make no comment as to the average quality of the asset produced. I only note that it's a very limited asset that's expensive to produce.

[1] Note that I'm not saying that the surveillance systems currently deployed provide access to 90% of everyone's daily activities. This is an illustrative example. However, it takes only a few minutes' thought to notice that the police's powers of surveillance are far greater today than they were in the late 1700s.

Either it needs a warrant or it’s fully open and people can start creating websites showing the movements of local politicians. This middle ground that municipalities try to carve out where it’s fully open to police without a warrant but not subject to FOIL laws doesn’t appear tenable for much longer. There’s been too many cases of police officers stalking exes, poking around the data for fun and such so it’s clear p…

Because of the scale: ALPR’s track where everyone is and was all the time. This allows entire categories of intimate information to be learned, that clearly threaten the civil liberties that the 4th amendment was written to protect.

For example, an officer sitting on a city street is very unlikely to learn where his wife goes every day, an ALPR search will answer that question.

An officer walking along the street making note of what he sees is very unlikely to observe and make note of the precise daily movements of someone in August three years ago, an ALPR search will answer that question.

The degree/kind distinction you’re aiming at is meaningless, it’s like trying to argue that shooting someone with a firearm is the same as shooting someone with a paintball gun in principle, sure but maybe one of them is orders of magnitudes morw powerful and impactful, and so deserves a different degree of consideration in how and when it is applied?

Scale is more about efficiency and cost, though. Plenty of people want more policemen patrolling the streets.

Great, now rigidly define scale...

You don’t need to rigidly define scale to demonstrate at a common sense level that there is a major difference between a couple cops writing down your license plate and a nationwide network of them entering your plate into a searchable ledger.

...so we only have 5 cameras, one at each entrance to our town.

Five cameras is less than what the number of police on duty are using.

Problem is that Flock CEO still has dirtbag access. Didn't he spy on someone at a conference in public view as part of a presentation of the technology?

Because the physical impossibility of a department doing that 24/7 every square inch of a city creates an expectation of privacy.

right now, neither needs a warrant. if searching LPR camera history starts to require a warrant, it probably wouldn't take much to argue that sending officers out to manually do the same thing should require one too. EDIT: i have no doubt that Flock and other ALPRs got so widespread because four ALPRs watching each direction at an intersection is basically invisible in comparison to four cop cars at every intersectio…

On a recent 3k mile cross-country trip I was shocked to see how prevalent Flock cameras were, even in tiny back-woods locations. I'm fairly certain you cannot drive long distances in the US anymore without Flock having a detailed record of your travels.
