Road rage is serious and can have bad results. I definitely feel sorry for both parties.
From my personal perspective, if what Attorney Davis says that Jeff Styles reported is true, Mr. Styles has some serious issues. If you know someone has a gun beforehand, and you are a normal person, you most certainly will not get out of your car and confront someone that has a gun, especially with a tomahawk. I know if it was me in that situation, I would leave well enough alone and get away.
If it smells like a duck and walks like a duck, it probably is a duck.
