On Friday, the Los Angeles Police Department launched the Tracking and Automated Graffiti Removal System (TAGRS) -- a program that allows law enforcement officials to track graffiti artists/vandals with their smartphones
. Under TAGRS, graffiti-cleaning crew members can use their smartphones to take photos of any vandalism, and upload the images to a LAPD database. The photos are then analyzed, and used to collect evidence for prosecution. As soon as suspects are identified, their names are added to the database, as well, which may help police link related incidents.
