I believe that if volume, processing, or accessibility of some new technology or information stream changes the access patterns to that information, that implies that the nature of that information gathering and accessibility needs to be re-evaluated. A cop calling in a suspect license plate is one thing, an automated system reading all license plates at all intersections and tracking every vehicle in a city is different, and should have regulatory or judicial oversight applied in light of the new access. The fact that any one of those plates could have been seen at each intersection by a cop who happened to be there does not mean that license plate readers don't change the nature of that information. A lawyer asking a clerk for a transcript of a call regarding a pending case is one thing. Transcribing all calls and getting a text message when someone called 911 yesterday and mentioned your name is a big difference.
