Clearly he was. There is a bit of mist visible for a moment. I was not the one who said the first line, it was what I was responding to.
The multiple shots, or some of them, could well have been counter-fire.
We can also assume the dead bystander died from Barney The Dinosaur farting. That’s is what the DNC is saying.
