The American Civil Liberties Union is trying to ban the use of license plate recognition (LPR) technology that supporters of the program say helped catch the Boston bombers and the man responsible for the attempted 2010 car bombing in Times Square.
The technology, which has become popular in the past decade, lets police officers potentially determine a person?s location at the time of a crime by running plate numbers through secure databases maintained by individual states. It is presently used in every state, the ACLU says. A former police commander familiar with both the Boston bombing and the attempted bombing in New York said LPR was a factor in solving both cases.
