Just a comment on a point already made - but it remains perhaps one of the more important points I take away from this: it's the high capacity pistol argument. How many guys do you see reload?
A gunfight will always be a "come-as-you-are" proposition: whatever you have in your hands when it starts is what you'll open up with. Since these LEOs only appear to have handguns available to them, as you count the seconds - ask yourself when would have been a good time to reload?
I mostly EDC small autos that hold around six rounds, with two spare magazines, and every time I see a scenario like this I wonder why I'm not packing a full-size pistol with double-stack magazines...
To add onto garryc's comment: '...you cannot have too much ammo
in your pistol when you are defending yourself'...
