Son of a gun activist was arrested Wednesday night and charged with an apparent road rage shooting on the George Washington Parkway. Police believe David Michael Keene, 21, shot a gun from a BMW on Sunday afternoon. The bullet shattered the window of a Mercedes Benz and became lodged in the driver's seat, just inches from the driver's head. Police believe Keene and the driver of the Mercedes were involved in a road rage incident along the George Washington Parkway just before the shooting happened. The driver of the Mercedes managed to get the license plate number of the BMW and report it to police. While I am not painting all gun advocates with one moronic move, I have to say that this is anything but positive for the pro-arms lobby.
