You Are Being Tracked By ALPRS

 

In July 2013 the ACLU published "You Are Being Tracked: How License Plate Readers Are Being Used To Record Americans’ Movements". Although this 37-page guide is a few years old, the information it contains is still valid today. 

The implementation of automatic license plate readers poses serious privacy and other civil liberties threats. More and more cameras, longer retention periods, and widespread sharing allow law enforcement agents to assemble the individual puzzle pieces of where we have been over time into a single, high-resolution image of our lives. The knowledge that one is subject to constant monitoring can chill the exercise of our cherished rights to free speech and association. Databases of license plate reader information create opportunities for institutional abuse, such as using them to identify protest attendees merely because these individuals have exercised their First Amendment-protected right to free speech. If not properly secured, license plate reader databases open the door to abusive tracking, enabling anyone with access to pry into the lives of his boss, his ex-wife, or his romantic, political, or workplace rivals.

And don't forget, it is well documented that Police Abuse Confidential Database Access to Stalk Innocent People.
