Drew my firearm today

Today I was driving on the highway, and see someone in the left merge lane, they are going significantly faster than the traffic, so I speed up a bit to let them in behind me. They decide to try and pass on the shoulder and then swerve into me to try and push me out of the lane. They begin flashing their high-beams and tail gating me a few inches from my bumper.I called 911, and informed them that someone tried swerving into me to run me off the road, and was now following me. I continued off at my exit, and got to a red light. At this point, they were still behind me, and continue being as close as possible to my bumper. When the light turned green, I didn't move, hoping they would pass me, which they did. They then proceeded to slam on their breaks, and get out of the vehicle. I told the 911 operator that they had stopped and gotten out of their car along with the license plate of the vehicle.The other person had gotten out with what looked to be a baton or a pipe, and were towards me. About 7 - 8 feet away from my car, I opened the door stepped out and drew. I yelled that if they kept coming at me I would shoot, they then turned around, got into their car and drove off. I waited until they were about a good distance away before holstering again, and picking the phone back up. I told the operator what had happened, and she told me that police were almost there and to just wait for them. They arrived, they took a report, and left.The lessons I learned from this were to first off, not get off on an exit until police are closer, or the other person has stopped following me, and that I really, really need a dash cam. Fortunately, drawing my gun I was able to deescalate the situation. via /r/CCW http://ift.tt/2j2CQcl
