We could also install cameras in every home and require people to wear a forever listening microphone at all times that the government can access at any time. This would stop a lot of crime. But I wouldn't call it successful. I guess my point is we need to have higher standards then this tech is preaching and since it is nothing like it seems, this is nothing more then a magic black box that the police would love to be able to use to pick people out of a crowd.
