Comment: Most in Datawarehouse in AZ

Many Police Depts use the system that stores all the data in a big data warehouse in Arizona.

Since it tracks your car across multiple jurisdictions they can search across a large portion of the USA all at once.

It is sold under the guise of finding the cars of unpaid tickets and fines (revenue stream).

It is used most often to find things where they do not know your license plate.
- They can find all the cars that might have witnessed a crime. i.e. You drive by someplace where something happened and 3 days later they contact you to see if you saw somethig.

- Also it has a live "Blue Pickup" search feature. So they type in "Blue Pickup" and it shows in livetime in all surrounding jurisdictions any blue pickups that were recently seen by a camera. Then they can fine tune from there. I think it can automatically APB to surrounding police so if a blue pickup drives near a camera it is falgged right away as an alert.

- It also does license plate stuff but I have been told the "fishing expidition" to find witnesses and the "blue pickup" search has been the most usefull.
