When I originally cooked this scenario up, I was thinking about a couple of then-recent events: the Trayvon Martin shooting and an incident in Texas where a buncha guys walked into a restaurant carrying rifles. In the picture I saw, one of these people had what appeared to be an M-16 slung across his chest, barrel downward, in a position that would have taken less than a second for him to grab, adjust to firing position, and begin shooting.
I was later told that the rifle in question was an AR-15, the civilian model of the same rifle, but without selective fire. Not being a rifle expert, I couldn’t tell the difference from the picture.
I was struck by Zimmerman’s defense in his trial, which was taken seriously, and got him acquitted, which as far as I could tell, boiled down to “Well, I was shadowing this kid in my car, and he freaked out and ran into this neighborhood, and the police dispatcher told me not to pursue, but I chased him anyway, and he ambushed me, and he tried to get my gun, so I shot him.”
This bothered me greatly. It’s okay to creep somebody out by following him, then chase him down, but if he fights you and you kill him, it’s okay? It got me to thinking about “I felt threatened” as a defense.
It also occurred to me that in parts of Texas, walking into a restaurant brandishing something that looks like an assault rifle is a very likely way to get shot.
Which made me ponder, and made me put myself in the Tom role. I don’t have a concealed carry permit, and I don’t carry a gun in public; I have no need to. But if some ape strolled into a public place where I was minding my own business, brandishing a rifle, what would I do?
The gun nut fringe position these days is “Well, if the teacher had had a gun, she could have returned fire on the little bastard, and potentially saved her own life and all the other children as well.” In practice, I can’t help but think it would lead to the exact scenario I described in the OP: Tom must make a split second decision as to whether this is a lawful and entitled gun activist… or a lunatic who will kill him and everyone else.
And the experiment changes when you change the circumstances, which is why I didn’t say where the McDonalds was. What if it was a theatre in Aurora, Colorado, and someone shot the idiot who walked in with the automatic weapon?
What if Tom was black? What if Jerry was black?
What if Tom had had his family with him?
For the most part, I agree: Tom shouldn’t have shot without more evidence. On the other hand, if he’d waited, how was he to know he wasn’t simply giving Jerry the time he needed to kill someone?
