Secret high-tech anti-graffiti detector installed in undisclosed SF Bay Area locations

The city of Richmond, CA  has a new weapon to thwart graffiti artists, at least in theory. KTVU Channel 2 News aired the special report on Monday detailing the effort: “the Police asked KTVU not to reveal what the device looks like or how it works but said once activated, it senses when someone is tagging a nearby wall. And when it does, the gadget alerts officers to the location.” At $1,800 each, it will be interesting to see this method stands up to traditional anti-graffiti measures, such as wall coatings.
