is a good guy with a gun"
Except for the rare circumstances in which the shooter kills himself, yes, that's how a bad guy with a gun is stopped. How do you propose we stop a bad guy with a gun...hit him over the head with a 'gun free zone' sign?
It turns out Alexis was armed only with a shotgun.
Last I checked, that's a firearm..a 'gun'. You know, the type of firearm your Vice President told us to get.
He was able to take down those "good guys with guns" in the building to then use their handguns to kill more people.
Right...and? Did the NRA, or anyone for that matter, say that a bad guy with a gun can never get the drop on a good guy with a gun? I don't think so, but you tell us...
What will LaPierre and the gun-nutters say now?
You realize how the bad guy was stopped, right? He was shot by a good guy with a gun, so I suspect 'ol Wayne will say that the only way to stop a bad guy with a gun is a good guy with a gun...and he'd be right.
Are you really this stupid, or are you just being obtuse on purpose?
