This thread has been beat to death, and I doubt that anyone is going to change their minds on this. Some of us believe that Gumm should have stayed in his car, some don't. Anyway, I usually don't like to muddy up scenarios or actual cases but just for kicks on this one, lets see if you think the same if we switch it just a bit.
Substitute, angry road rage for, they just had a fender bender at a stop light or parking lot, whereever. Turney gets all irrate and heads towards Gumm, and Gumm exits his car with pistol in hand. Is Gumm still right to exit vehicle with pistol in hand, or should he have stayed in his vehicle while the rage was taking place? This is the same basic scenario as far as legal issues go. If your answer is yes to this one that Gumm should have exited with gun in hand, we definately need to start a refresher course in concealed carry laws IMO.
