Kenneth W. Lilly, an armed security guard, got into an altercation with a 78-year-old school bus driver on a snowy Minneapolis area interstate Tuesday. In a fit of apparent road rage, Lilly exited his car, approached the bus and fired five shots at the driver.

The Minnesota Department of Transportation has released this video of the incident and the subsequent arrest.
