I don't have a problem with the technology, I do worry about the oversight however. Look, using modern technology to make our streets safer is a good thing. I want the police to be able to ID criminals, catch them, and prosecute them in a timely manner. I am also not so naive to believe that there will not be instances wherein the system is abused by some of the people running it. Even if the current group of people are all good people, sooner or later someone is going to screw it up.
Any concerns I may have with this are firmly due to the general lack of proper oversight on policing, which allows a small number of bad officers destroy any trust built up by a large number of decent ones.
