alt Hacker NewsI really don't understand why they do trials for this. What would be the failure case for the trial? "We carried out the trial for 6 weeks over X period of time, we arrested Y people, at that rate we've decided this is not compatible with modern liberal democracy, we would've traded a free society for Y+2 arrests over X period but we just didn't quite get there"?
As suggested by other people - this is just going to be used to identify, infiltrate and disrupt the numerous peaceful protests that the police aren't keen on in London.

All due respect but I am not totally against police dealing with protests. I am against this Orwellian surveillance stuff. If you want to police so people can deal with day to day things like go shopping without being harassed or freaked out I am all for that. But do it the old fashioned way.
It's a technology. What you could do with it, and what you should do with it are completely different things.
If you follow the links there is a lot of information about the trial, including a whole series of documents identifying the legal framework that authorises LFR, including rationale under GDPR, Data Protection etc.
Of course, this technology could be used for bad purposes. But within a democracy, policing happens with the consent of the people, expressed through various channels including legal (parliament and local government) and police commissioners. What is interesting is the way that these frameworks are used to constrain the purpose and extent of this processing. For example, at the moment the images on the watchlist can only be drawn from custody images.
The police already have powers to seize CCTV and door-cam imagery in order to investigate crime. They need a warrant from a judge - so it isn't justified without good reason such as serious crimes. This is the way you constrain these things - you put the regulatory framework around them. You can't put the technology back in the box, so you put rules and expectations around how it is used.
They are prepared to arrest 90 year old protestors at Palestinian matches for Israel, they won't stop until all critism of that illegal state is silenced.
The failure mode is incorrect detections. If the automated system says person 1 from camera 1 is the same as person 1 in camera 2, and then extrapolate out to 10,000 people and cameras, and then don't get it wrong. Because the BBC is never going to let you live it down if the person they arrested for stealing kinda sorta looks like the guy that actually did the stealing.
Just a guess, but I would think that a significant motivation for doing a trial is to ensure that the frog is boiled slowly.
Opposition can now be met with "it's just a trial, relax". Then you expand the trial a bit. Keep running it until the discourse moves on. And then a few years down the line, when you roll out the full system and people complain, you can counter with "these people are exaggerating their concerns, we've trialled this for yeaaars and there were very few problems!"
How would that work? Easiest way to stop protests is to block off the area of the planned protest and arrest people who try to enter it. It’s not clear to me how facial recognition on the tube would help from a practical point or view.
Also, this seems to just be a trial expanding existing time and location scoped deployments of live facial recognition into a new environment, rather than a trial run for always-on live facial recognition across the tube network.
If I were to guess, they may have some "test" users (people who are involved in this) who are on the watchlist, they do their regular commutes and see if the system picks them up each time.
For this system there is no requirement that criminals faces are used to test it.
