Ah.. Colorado, Home of the Rampages. http://msnbc.msn.com/id/5139598/

"One officer, later identified as Trainor, was perched on top, firing shot after shot into the top and once dropping an explosive down the exhaust pipe. “He just kept shooting,” Moore said. “The dozer was still going. He threw what looked like a flash-bang down the exhaust. It didn’t do a thing.”

"The scene was reminiscent of a 1998 rampage in Alma, another town in the Colorado Rockies. Authorities said Tom Leask shot a man to death, then used a town-owned front-end loader to heavily damage the town’s post office, fire department, water department and town hall."
