The cops will find all kind of uses for the data.
For instance: What people from the good part of town are parked in the bad part of town on Friday night? Those people get red flagged automatically in some software because they are now suspected (by the computer) of possible drug purchases or whore mongering.
They could monitor bar patrons for frequency and time duration. And then target them for ‘traffic safety stops’ when they are actually trolling for some money making DUIs. You might think that is OK because drinkers shouldn’t drive but this is just an example.
The possibilities are endless, and if the municipalities get on the bandwagon the software developers would be happy to provide the Orwell Code.
They would very bored with most of our data. The Feds can get much more useful data from your cellphones.
