I was driving home from work one afternoon last week. Quickly passing me by was an aggressive driver in a small SUV. Thought to myself, "what a jerk" with the way he was weaving in and out. Right in front of me was a pickup truck. He wanted to get into the left lane, put on his turn signal, and began to move over. Aggressive driver in SUV accelerated quickly to prevent the move. pickup driver swerved a bit to avoid hitting SUV... but then accelerated a bit and made it into the lane. By this point, I am side by side with aggressive driver in SUV, and I look over at him just as he pulls out a gun from under his seat and points it at the pickup driver who did nothing wrong. He pulled the weapon, rested his wrist on the steering wheel, and clearly aimed at the pick up, who turned left at the next intersection. I was clearly convinced he was going to shoot for a brief second, but then put the gun away and drove on. I hit brakes a bit to slow up and get behind SUV driver and record license plate, and then I call 911 and report. 911 Op takes as much info as I can give including license plate #, description of vehicle etc, and then instructs me to pull over somewhere so they can send a car to take my report/statement. I do, and give 911 Op address of where I am. Very shortly thereafter, unit shows up, two LEO's. They come up to me, and I give them report and description of person who pulled the gun and description of vehicle. LEO takes my name and phone number, I offer ID but he refuses it, and then.... wait for it... LEO drops the bomb on me. "Thanks. We'll tell others to keep their eyes open, but we can't try to go after the guy now.... We'll just have to BOLO the guy and see what happens. Have a nice day". Given that I had the license plate #, a clear description of the vehicle, description of the man, and I could clearly see it was a Glock (19 or 17 size)... why not go get the guy to at least question him?
