Armed Self Defense

the in n out shooting
note that the 'off duty' cop is not the same person as the 'retired' cop, that is not made clear
don't I see 4 people with guns besides the 'shooter' ?
you have the retired cop [injury made him unable to use gun], the off duty cop [shot and missed], the civilian [also missed], and am I nuts or when they show the off duty cop isn't there some other guy there with a gun? I'm thinking he maybe got shot, referred to as the 'good samaritan' later
I won't count the lady who picked up a jammed gun and didn't unjam it
