Don't hit anyone. Why would you? Then he'll cause more problems for you. I definitely wouldn't push any truck out of way or hit anyone. I'd document him preventing me from leaving. Then I'd push his buttons enough that he'd lose it and get him to commit battery on me. I wouldn't defend just take it. I'd have a good attorney and pay for my own independent crime scene team to document how he beat me. I'd pursue criminal charges against him as I committed no crime and he is violating my rights. I'd file a complaint with the Attorney General. You can't stop someone and prevent them from leaving. Maybe if it was some felony like muder but not for allegedly hearing a shot. Then I'd sue him civilly making sure to get a change of venue to the city where a jury would side with me. I'd collect his retirement checks from the state of Alabama and take all his land from him.
