Well, off the top of my head, the Ft. Hood shooter was taken down by a policewoman with a gun. Remember that we don’t allow military personnel on military bases to have weapons, which he knew since he was a member of the military.
Just an example that these people are full of it.
Let’s not forget the lady in Colorado Springs that took the guy out at the church. I guess “she” doesn’t qualify as a good “guy”.
She exchanged gunfire with him but she did NOT take him down.
“Sergeant Munley said she heard Sergeant Todd shout at Major Hasan to drop his weapon and then heard the gunfire that ended the confrontation.”
Sgt Todd took him down.
