I was shocked last night when I was watching CNN and a 2A supporter was engaging the host and mentioned the citizen's involvement in this incident. Of course I came here and read the last page of replies for details. I am outraged that this hasn't been mentioned in the mainstream media (but I'm not shocked). The host of the show (Piers Morgan) actually said that no civilian/ armed citizen has ever stopped a mass shooting and that it is a "myth" that it has been done.
I would highly encurage anyone on this board who knows of a story or has a link to a news report of a citizen stopping a shooter to please e-mail it to Mr. Morgan at CNN.
