The problem with this argument, from the shop's point of view, is that the UK is in the middle of a shoplifting epidemic. The policing resources simply aren't there to deal with small scale (or even flagrant and much larger scale) shoplifting. It now seems to be rare for police officers to attend reports of shoplifting at all. And so effectively shoplifting becomes legalised, which is obviously hurting the big chain stores financially and potentially devastating for smaller shops.
Shops are trying to find some way to respond to this to protect themselves. They typically tell staff, even security staff, not to get physical with shoplifters as they walk out, not least because the risk of something worse happening and the business becoming liable for it is significant. But then the shoplifters know this and some of them will just walk in and openly empty a shelf into a bag and walk out again without paying because they know no-one will try to stop them.
Shops also know that our court system is completely overwhelmed at the moment and there is little chance of bringing any successful civil action to recover damages from shoplifters who aren't even being arrested by the police and put through the criminal justice system.
So what do they have left? Basically, they're trying to spot the "usual suspects" and refuse them entry in the first place, which is a less risky proposition in terms of potential for physical violence and quite effective because a lot of shoplifting is done by the same people, or they're trying to make it more physically difficult to steal goods, for example by using locking systems or keeping high value items behind counters where customers can't just pick them up. But these systems aren't perfect, far from it, and what we're discussing here today is one of the significant problems.
Obviously this kind of technology can have very bad consequences, as we see here. I don't think it should be used if it's not highly reliable, given the potential harm done in cases where it gets something wrong. But I do have some sympathy with the shops who are looking for something -- anything -- to reduce the threat they're facing because the rule of law has failed in retail settings.
