my boyfriend was at a green light and the car in front of him stopped which caused him to stop in the middle of an intersection, he honked, the driver from the car flipped him off and she took off, while going down road she break checked him, lane split into 2 and he tried to pass on her left she tried to side swip him so much so, that he had to go into the other directions lane, he got in front of her and she continued to ride his bumper. He stopped his car got out , pointed at her through the windsheild and said "if you keep driving like that your going to get you head bashed in." got into his car and drove away. she apparently is bringing him to court for criminal threatening and the officer who informed of this told him he can go to jail for 5 years if found guilty. Is that possible?
