The shooting spree in Chicago in the last day, I think, speaks volumes about how the mainstream media covers news. This is a horrific day/night of shooting, yet it isn't getting the coverage of the recent shootings in Aurora, Colorado and Oak Creek. Nobody as died, so far, in the Chicago shootings and they didn't all happen in one geographic location. These differences apparently are critical to the media.
They would deny this, but to the MSM body count is important and the count right now in Chicago is zero. 50 people wounded isn't as big as 10 people dead to them. For all of the handwringing about evil guns, gunshot injuries pale in comparison to gunshot deaths. "If it bleeds it leads" has been replaced with "if the body is cold it is gold."
Additionally, the media also seem perplexed if they can't point their camera in one convenient location; a movie theater or a Sikh temple. They seem to believe carnage is only newsworthy if there are bodies stacked and that they are stacked within the walls of one building. The media mass killings as an opportunity to soap box against guns. But the reality is the bigger the mortality rate, the more excited they get about guns.
