At engagements from 1-4 yards, people don't fucking miss that often.
Someone doesn't need to be a practiced marksman to make standard shots at that distance. Anyone can do it, which is what makes guns dangerous in the first place. Ware dumped his magazine into two "trained" guys at close range and they had no time to do anything.
Rittenhouse should have made it obvious, but just because someone is an unathletic nerd without motor skills doesn't mean they can't be dangerous.
Thus, chasing down or tackling a maniac with a gun is a context-specific action. Only worked in the Rittenhouse case because his back was turned.
Don't be stupid.
Thank you for stating this better than I could have.
