Again, I'm not taking anything away from the guy. I commend him for all the reasons you mention. No argument from me whatsoever. But in my world, when someone starts shooting up a mall you're in, and you have a gun on your hip, fleeing out the back door or grabbing your phone to become a YouTube star aren't viable options. He did what he had to do, simple as that, and if he hadn't done it he likely would have been counted among the dead with a bullet in his back.
"What he had to do, plain and simple" was something virtually nobody else in his position has done, at least not in the last 20 years in the US. This is the kind of monumental CCW response.
So, LOL, you can't take anything away from the guy. Do you know of any other instances where a mass shooter was better handled by an average Joe? By average Joe, I don't mean off duty cops, retired cops, gun range owners, firearms instructors, Navy Seals, or security guards, but just some dude with a CCW? I don't mean guys that stop the shooter after the shooting is over. How many can you list that did such a good job? This isn't exactly rhetorical. Think about it. How many mass shootings have been stopped by truly average people and stopped so well?
Your world view is great, but as it turns out, lots of people have your world view but never manage to be at the heart of mass shootings and manage to react so quickly and so decisively with so much skill. It all sounds pretty easy. The responder just needs to be highly decisive, skilled, prepared, and a good bit lucky to be in the wrong place and the wrong time for something terrible to start happening.
Let's backtrack a bit. How many mass shootings have you been in or at in your life? I have been in zero. I have known plenty of people who have been in muggings, store robberies, a couple that have been in home invasions, but I can't think of a single person that I know person who was in a mass shooting. Strangely, or not, very few people on this forum have been in mass shootings as original players, though some LEOs here may have responded to mass shootings.
This is an Anthony Swofford sort of problem. He was a first Gulf War sniper. He had all the training and capabilities, but was virtually never in a position to use what he had learned and even when he was, it wasn't pulling the trigger.
So there is nothing to take away from our Hero. He was the one person who was there in a crisis, in the kill zone, who not only knew what to do, but knew how to do it and did it exceptionally well. He didn't die or get hurt and he didn't kill or injure the wrong people. He won Game of Thrones without even knowing he was going to be a player or what the rules were for the day. Not many people can say that.
Dicken? 10 shots, 8 hits, 40 yards, <15 seconds on a hostile target with a pistol.
You want to talk about people doing what they had to do in a mass shooting? We can look to Luby's and the multiple individuals who did what they had to do and attempted to openly charge the gunman and were summarily gunned down in the process. We can look to all the others who didn't attempt it. It isn't enough to
do what you have to do, but to be able to do it well, decisively, and in a timely manner.
Even better, he didn't get shot by the cops afterwards, like Johnny Hurley.
