Some days, it would be easy to mistake the Metro Taxi dispatch center in Denver for a police station. Traffic and crime incidents are recorded in a special logbook, as drivers call in descriptions and locations to police.
It's part of a program called Taxis on Patrol. Just a day after the program began, a cab driver helped police make an arrest for a fatal hit-and-run. In the months since, eyewitness calls from cabbies using a bulletin system similar to an Amber Alert have led to hundreds of arrests.
