Well, I was wrong on all counts except one, and that was the military connection. Also somewhere along the way it occurred to me there were two people involved.

I'm wondering...... if the older man didn't do the first few shootings, and the boy did the last two.... I dunno.

I doubt that anyone actually SAW these people in action. By the time anyone heard a shot and looked around, they were already on their way.

And again..... we don't know yet that These Are Them. I think it's a pretty good bet, but let's not count all the eggs just yet.
