It's been said plenty but after Sandy Hook I don't see any level of mass murder making people change their minds.
i think it's possible (though i'm not sure how likely) that there being videos of mass shootings (now and going forward) could make them have a different effect on people than something like Sandy Hook.
the videos of this are terrifying. the sound of automatic weapons fire is terrifying. as dumb as it is, people might be more affected by something like this where this is audio/video than Sandy Hook. that's just part of our nature, i think. maybe wishful thinking on my part, but i was shook after watching a couple of those cell phone videos.
