I would be interested in knowing both what kind of fabrication occurred, but perhaps I’m not curious about how it was discovered? Did the defense use some sort of tool to debunk? Was it just an obvious deepfake etc? Or was it the officer’s ineptitude that got him caught?

My experiece with whatsapp family groups is that a lot of people over 40 can't detect the most obvious AI fakes (e.g. Studio Gibli clones, or three handed people), so they share the most stupid stuff as it was real, while youngers seem have an instinct to detect AI but can't tell exactly why they know. I can picture a cop fabricating images that are obvious, even with a watermark included, while totally convinced tha…

To be fair, this is Derbyshire in England. They are often a bit overkeen but they are not exactly Homan Square. I think there have been less than two dozen police involved killings in the whole of the UK in the last six years, and that's in a population of seventy million people. It's about 2% of the equivalent US figure (which averages 800 per year in 340 million people)

It doesn't make much difference if you perform similar practices in a different country. UK police are just like American police.

who are exactly the same as the Russki police, right? Bloody hell...

you're quite right, every single one of them is actively trying to kill each and every one of us. To consider any other possibility would be hysterical.

... Police in the united states have more than a century of flagrant misconduct under their belts. They protect their own, they almost never face consequences for killing people, they are frequently corrupt, they are frequently biased. Here's a couple fun examples: https://www.wgbh.org/news/local/2026-06-05/boston-law-enforc... https://www.reuters.com/legal/government/la-is-investigating...

This is the UK, our cops don't even carry guns.

This is why: - the whole roll of negatives was prime evidence; - police forces were one of the biggest users of Polaroid instant film. And moreover, who had a darkroom and the skills to edit substantially a picture? Whereas here we have nobodies being able to generate pixel-perfect fake "evidence" from the computers they already have.

You can burn negatives. You can fake polaroids, really, just think about how a camera itself must operate and you'll see why instantly. Darkrooms used to be far more common before digital photography my Junior and High school both had them. What makes evidence "pixel perfect?" What digital photographs don't have to involve a chain of custody? Literally the first question the defense will ask is "how did you get this…

You are just too young to know.

Eh. It was some kind of hash of the image. I was not involved in that project, so can't tell you exactly how it worked, but the images were "signed," and someone figured out how to "re-sign" an altered image. I think it was a fairly well-known technique.

Which still sounds like your employer was simply incompetent because why was any type of perceptual hashing scheme even involved? Signing digital data with hardware secure tokens is a commodity capability in the iPhone many of HNs users are reading this site with.

> your employer was simply incompetent

You’re probably right. This is easy, basic stuff that any recent college grad can do with their eyes closed.

I think this has been around for not so long https://en.wikipedia.org/wiki/Content_Authenticity_Initiativ...

This was quite a while, before that.

My girlfriends been having me watch law and order svu with her and to be honest it doesn't really even seem trustworthy with how they want to present it. The psychologist guy especially will come up with some wildly detailed assertions about who the criminal is based on nothing

Are we really going to go to a fictional TV show now?

There is a reason such shows are labeled "copaganda" - it affect people's perception of police and their procedures. It makes the dubious seem less dubious and more believable. I very highly doubt any jury is made aware of the rate of error or unreliability of the this stuff.

i do wonder, that in the age where we have image and video creation out of the bag, whether or not this will result in whole classes of evidence becoming completely unreliable.

There's a big gap between "theoretically unreliable" and courts actually recognizing that, unfortunately. Lots of forensics is much more dubious than CSI would have you believe.
