Number (2) on your list is already happening.

It certainly gives the media --who already have a bias toward anti-gun advocacy-- full license to slant the story in that direction. I heard some Democrat politician ranting yesterday about using this to advance a ban on automatic weapons. Never mind that this "Bryce Williams" clown DIDN'T USE an automatic weapon to kill these two Virginia reporters.

This angry guy's online rant reminds me of Christopher Dorner's online manifesto, roughly two years ago. And like that case, God knows the liberal media doesn't want to report on how the stoked rage of these two killers leads straight back to their own racial demagoguery!
