I have never hit anything but years ago when i was doing work exp, walking home on rooty hill RD NTH some cop cars went flying past with sirens on, and bad luck for the old guy next door to me, he was walking his rotty in the park. Once it heard the sirens it took off and run under the front wheel of the cop car doing about 70-80, as the cop braked the dog got stuck under the front guard. He asked me to help him pull it out, so i did, then he took out his gun and shot it in the head. He then left to go to the robbery and left me there to explain what happened to next doors dog. The cops came back eventually.
