Now cutting-edge forensics makes it possible to trace the offending matter back to its source. A citizen commission in Dresden, Germany, has overwhelmingly recommended a scheme in which DNA samples would be collected from all dogs when their annual license came up for renewal. Within one year, a database of Dresden's registered 12,500 canine residents would be complete. Sanitation workers would carry feces-sample kits and submit evidence to a forensics laboratory, where scientists could easily match doo to dog. The dog's owner would then be promptly fined up to $600. Dresden's commission targeted a break-even point at about seven months. Afterward the city stands to turn a profit.
