I am begging people to realize that police do not use this technology is not a "jumping off point" or an "investigative lead"--the computer spits out a name and police arrest that person without follow up. How many people have to spend months in jail "by accident" before we consider the danger?
A San Diego man spent one month in jail for a crime he didn't commit, after San Diego Police misinterpreted a hit from a license plate reader.
