This is conflicting, on one hand it's certainty within the right of a store to bar people who shoplift, it's really an imperative to do so. The petty crime issue the retailers here are trying to counter is a real one.<p>But this application it feels like falling down an increasingly slippery slope.<p>Sure, today, it's just "send an alert and the store can do what it wants" but how long until that transforms into a de facto ban from the premise? Scan the person on the way in and flash their picture and name up on a TV and tell them they are trespassed from the store and if they don't leave within 60 seconds the police will be called. You can even automate that!<p>Sure, today, it's just "share with nearby stores" but how long until the database starts to be centralized and extends across whole states, countries or even worldwide? An argument could be made that people who are farther away from home are more likely to commit petty crimes since they have less worry about repetitional damage or harming their own community, so, obviously we need to share this data nationwide or even globally!<p>This facewatch company is going to have an imperative to add people to it's database and obviously sell subscriptions to access their data centrally, they aren't going to have any imperative to fairly adjudicate removals or false positives.<p>I can easily see a system like this ending up like credit rating bureaus with a few large companies aggregating data into a score which stores can use to deny entry.<p>Even if you ignore data errors of any kind and ignore false positives entirely, the concept of a relatively minor indiscretion resulting in a permanent, global, ban from any store using this technology is positively dystopian. It deeply reminds me of two of the better episodes of Black Mirror, White Christmas (the end -- you know what part I mean) and Nosedive.<p>The fact is though, there is a legitimate need for some kind of change to solve the retail theft problem and I don't think this type of technology is going away.<p>I'm generally not to argue in favor of regulation, but, this seems like this technology is going to require regulation around disputes as well some kind of regulated civil penalty list (shoplift less than $100 of merchandise on your fist offence and you're banned for at most 1 month). The real problem is that we (the US) have done a terribly poor job with regular credit scores and I can not imagine us doing a better job with this.
