I'm confused as to your conclusion that the "general public" isn't talking about the shooting. What metric are you using for that? Your own Facebook feed? I don't know how much I would assume from just Facebook.
The news outlets I follow have coverage of the shooting and there are a thousand plus comments to each of those stories. Is the news coverage as rabidly sensationalistic about this shooting as it was about the CO shooting? Maybe not, but that might not be a bad thing. For better or for worse, the CO shooting provoked a media and water cooler-discussion frenzy, but that hardly means that the coverage and discussions were all intelligent or worthy. I'm more interested in the quality of the coverage and ensuing dialogue, not quantity.
