I don't even have a problem with every cop being equipped with an automatic ALPR... So long as the data is not retained. I do believe that we need better auditing and oversight in response to the availability, but it's not a great evil that an APB can be virtually guaranteed to catch a car... So long as we're using them carefully and judiciously, in response to immediate and recent threats or a clearly understood long tail. There's supposed to be a balance of power; it's not evil to give the police new powers, but it is evil to give politicians unanswered and unlimited tracking of the movements of anyone they so desire.
