Discription of Events: WARNING! THIS LUNATIC IS EXTREMELY VIOLENT AND EXTREMELY DANGEROUS! CALL THE POLICE IF YOU SEE THIS MURDEROUS PSYCHO ON THE ROAD! I was in the far right lane on Renner and was stopped at the red light at Renner and Renner Pkwy. The was one car in front of me. This psycho in the Caddy was in the middle lane on Renner...the lane next to me. When the light turned green, the car in front of me started to go, and then I started to go. Then as soon as I started thru the intersection this MURDEROUS PSYCHOPATH came speeding up beside me and HARD JERKED HIS CAR BARELY AN INCH FROM MY FRONT BUMPER! He was SO CLOSE to my bumper, all I saw was his rear windshield in front of me, and a bit of his trunk hood. I did not see ANY of the rear of his car!!! I had to hit my brakes and luckily there wasnt anybody in the middle lane so I swerved over into it to avoid a collision! Then somewhere down Renner, I ended up back in the right lane and I noticed this asshole was RIDING MY REAR BUMPER!!! And he STAYED ON MY REAR BUMPER until we got to Custer street, then I looked in my rearview mirror and saw him TURN RIGHT off of Renner onto Custer from the CENTER LANE, CUTTING OFF VEHICLES IN THE RIGHT TURN ONLY LANE!!!!
