Always armed with something. Most people have cell phones these days and can call immediately. Hopefully atleast 1 person got the license plate number. Besides you of all people should know that you never know who's carrying a gun here in Texas. I love our concealed handgun law. :)
I think that's a waste of time. I tried calling 911 a couple of weeks ago while watching a road rage guy threaten another driver with a car.... in the middle of a busy road that he had stopped in the middle of. The 911 operator (a member of Jessie's minority) was like.. you can't file a complaint unless he's waving the gun at you. Seriously.... I finally hung up on her after about 30 seconds of frustration. Fortunately the guy didn't shoot anybody. But if I had shot him or something.... I'd be in jail for taking the law into my own hands.
