Big Brother Technology in Squad Cars?

It's not the City of London yet, but Los Angeles is expanding the use of video scanners by the LAPD. Automated recognition systems mounted in patrol cars can process 1500 license plates every minute. A cop with a computer can handle about 100 in a ten-hour shift. The technology is great for solving auto thefts, picking up wanted felons or monitoring sexual predators' movements. But it also collects and stores vast amounts of data about innocent people. Peter Bibring is a staff attorney with the ACLU of Southern California.
