Hamden police have a new high-tech surveillance vehicle to help them catch drug dealers and other criminals in the act. The vehicle, purchased for $24,000, has been outfitted with more than $100,000 in surveillance equipment. Most of the money used to buy and install the equipment -- some $90,000 -- came from the town, largely from assets seized in drug busts, says Deputy Police Chief Steve Cahill. A federal block grant provided another $10,000 for surveillance equipment, and the rest was donated. Cahill, who served on the Statewide Narcotics Task Force in the mid-80s, says, "I realized as a narcotics officer how important this kind of technology is. There's no evidence as convincing as a video or photo of a drug deal."
