The Text-a-Tip line will enable citizens to send anonymous crimes tips into the SFPD, and the Internet-based tool lets the officers respond for more information. The program has been deployed in other departments in 40 states, and it reportedly has been useful in gang activity cases where tipsters fear reprisal.
I'm not naïve enough to think a few commuters sending police "OMG! cRimnalZ on Bus 33" will put an end to all crime in the city, but this is a signal that the SFPD can leverage the technology around them to help them do their job better. Good police work will always rely on the bravery, intelligence, and hard work of the boys in blue, and tech like this SMS program can assist in their crime-fighting mission.
