The current issue (Feb. 2012) of small magazine published in British Columbia, Focus, contains a disturbing article by Rob Wipond, entitled Hidden Surveillance.
“This will revolutionize the way we police,” proclaimed Vancouver police in The Province, a Vancouver newspaper.
The technology is called Automatic License Plate Recognition (ALPR). I'm quoting Wipond's article:
The RCMP and BC government piloted ALPR in 2006 and have expanded it rapidly. BC now has 42 police cruisers equipped with the technology, including one with the Victoria Police Department (VicPD), one in Saanich, and two in our regional Integrated Road Safety Unit.
