I’m not sure how most people think they will look when they go through something similar.
You won’t get to pick how you defend your home or somebody else.
I believe Mr Wiliford, the good citizen who stopped the murderous rampage in TX at the Baptist church, did so barefoot. He chose to grab his rifle rather than his shoes. There’s a ton of home defense stories about folks protecting their property in their skivvies or less.
The first guy that responds to a similar incident all kitted up is going to be scrutinized for how he did it as well.
These folks could use some better gun handling skills for sure, but all in all, they did okay.
