And that is the problem with these laws. Dunn didn't have to actually see a gun. All he has to say is he feared for his life. So, this guy gave me a menacing look, he reached into his pocket for what could have been a gun, then I shot him because I feared for my life. That's a bit of an over-simplification; but a situation like that could very well take place - especially if people see that they can claim SYG for almost any situation and become more willing to do so as they see people getting away with what would be considered murder in any other state without a SYG law.
Dunn didn't have to actually see a gun
i do believe that he did see something
i believe the victim was holding a set of numb chucks by one handle
which was sticking up a few inches in the window
and mistook as a shotgun barrel
you can see a set of numb chucks in the suv
from the crime scene photos
i also think the door was open
when dunn fired the first three shots
