I cut him off on the freeway and he side-swiped my car in retaliation. When I pulled over he opened my door and threatened the break my jaw. An 'accident' report was made by both of us to the highway patrol. I have no witnesses, he has two who would corroborate his side of the story. My car was damaged, his was not.
What can/ should I do? Who do I speak to? Would a civil case be affected by whatever the 'accident' report says? Is it pointless if I have no witnesses and he has two?
