Face recognition software is making real advances and one wonders where we might want to apply it. Would we, for instance, want to take all security cameras and load in a database of missing children so that the camera can be alerted and can alert a person if that child happens to walk by the camera. Would we stop there? Would we also not say, “Let's load in a database of known or suspected terrorists and look for them in airports in other places?” And would we stop there? Would we say "let's take every wanted criminal, everybody that has an APB out on them and look into the cameras and ask if any of them walked by one of these cameras?" But would we stop there even? Would we take a database of every deadbeat dad, everyone who is behind on tax payments, everyone who has unpaid parking tickets and all the rest and load them into the camera? It's a technology that has no easy lines, and our application of it will undoubtedly be a slippery slope. We can't really know how far we will want to push the technology, but if history is any guide we will likely push it as far as we can.
