I personally have no reason to. Fight or flight does funny things to people and it take a minute to realize you're shot most of the time. It also stands to reason there were a lot of misses.
I get that.
He looked away from Spaide at shot no.1, with a brushish movement of his shoulder.
Reacts very clearly to shot 7, as does the wife before getting hit with no 8.
Hard to know with footage like that.
It's the sound that bugs me. Not necessarily the lack of blood, from apparent headshots to the wife. Though you can see prints being put down in the snow.
Reverb is funny, but I don't think it's going to increase the sound of a handgun to a described ar style weapon from the article.
