Knife Weilding Man Jumps on Police Car, Later Run Over by Cops - Dash Cam Video

This is truly amazing video from the dash camera of not one, but two police cars in Nevada, Iowa. Here's more from WHO-TV:

Nevada Police officers say they were protecting themselves against a violent man, but the man's family believes one of the officers intentionally hit him with his car. Thirty-three-year-old Eric Peterson is in critical condition after being hit by a police car Friday night.
The Nevada Police Department released the in-car video of last Friday's incident. It shows Peterson, armed with a knife, jumping on a police car and then running after it. Moments later, the video shows a second police car hitting Peterson.
Nevada Police Chief Mike Tupper defended his officer's actions, "I'm very saddened this has occurred, but it was not caused by the police officers. The officers were confronted by a very violent and dangerous person who was armed with a dangerous weapon and they had to protect themselves."
