I'm not a Suarez guy, Ayoob guy or anybody but a Sarge guy. When the balloon goes up, none of them will be holding my hand. But Gabe is dead right on all counts here. This stuff, and incidents like the North Hollywood Robbery, are precisely why some of us zero our carry guns for 50 yards and work hard at that distance.
Also, kudos to PawPaw, especially for post #8.
I have no truck with any private citizen who avoids a confrontation with a rampaging active shooter. If you do make that decision, channel Crazy Horse:
"Hokahey, today is a good day to die!"
Then fight like hell until it's over.
