How does live facial recognition work and how many UK police forces use it?

Here's something that might surprise you — since 2020, London police have been using live facial recognition, and now, the UK plans to roll it out nationwide. According to Robert Booth writing in The Guardian, this technology claims to be as revolutionary for policing as DNA was decades ago. But here’s where it gets tricky — supporters say it helps catch criminals faster, saving lives, while opponents warn it could violate civil liberties and unfairly target minorities. And the oversight? It’s lagging far behind the rapid development of the tech, raising serious concerns about misuse and errors. For instance, some shoppers have been falsely identified, struggling to clear their names. So what does this mean for you? As police expand these cameras, the debate over privacy and bias won’t go away. If this pattern continues, the next phase of law enforcement will be driven not just by technology, but by how we choose to balance safety with individual rights. That’s the real challenge ahead.
