its because the obama admin wants to create hot topics, one of which is gun control. it's all about saying a problem exists, so you can say you're going to fix it, and even appear to fix it, because there was NOTHING to fix in the first place.    you'll see more news about gun violence being made national, but that's just because it's a hot topic.       one thing a keen mind learns about the news is there's a bit of everything going on all the time, it's just what news chooses to focus on that makes something appear more prevalent.
