A guy on a Harley was in the lane right next to me. Basically he rode straight thru an intersection on a green light and some guy turned left right in front of him. He clipped the front bumper with the left side of his bike and went flipping head over heels down the road. When I got to him, he was alive but from his left knee down was GONE. Just some shreds af meat, I mean nothing left. The ambulance got there in minutes and the airlifted him out. The guy who hit him was walking around like nothing happened! I wanted to beat the Fk out of this guy I swear.I ended up waiting for 3 hours to give a statement. I hope he gets his ass sued off.
