Killdozer | Original Footage | Marvin Heemeyer got screwed for the last time

Maybe he shouldn't've oughta done that, but what they did to him, I can't blame him.
Corruption breeds destruction.

Marvin Heemeyer, an American automobile muffler repair shop owner, modified a Komatsu D355A bulldozer and used it to demolish numerous buildings in Granby, Colorado, on June 4, 2004 causing $5-7 million worth of damage. This modified bulldozer, nicknamed "Killdozer," was armored with layers of steel and concrete, making it immune to small-arms fire and highly resistant to explosives. The undercarriage was it's only real weakness.

He planned the attack for 18 months. During the rampage, which lasted about 90 minutes, Heemeyer destroyed 13 buildings, including the town hall and a former mayor's house. The local police and the Denver SWAT Team fired about 200 rounds of rifle and handgun ammunition at the Killdozer, but all the bullets harmlessly bounced off its impenetrable metal hide.

The incident was a result of Heemeyer's long-standing grudges against Granby town officials, neighbors, the local press, and other citizens. After the bulldozer became stuck in a hardware store (because the radiator blew), Heemeyer took his own life. No one else was injured or killed.

The primary motivation for his attack was his opposition to the construction of a concrete plant near his muffler shop, which would harm his business. Heemeyer was also upset about zoning disputes and felt that local officials were corrupt and unfair. He recorded audio tapes explaining his motivations, stating that he felt it was his duty to carry out the attack and that God had blessed him for the task.

Some supporters of Heemeyer online view his actions as an act of patriotic civil disobedience against a corrupt government, though this perspective is disputed by some.
