I think the RFID issues are certainly serious, but it's a different matter than the photo use.
Today they use all sorts of computer processes to sort through information and detect patterns or similarities that could help prosecute criminals. I'm not sure how using photographs would be any different from a legal perspective...although I'm also not a legal expert.
Is there room for error, sure and a lot of it. But mistaken identity is already accounted for in the process.
