On The DMZ, Bill and Matt react to the bombings at the Boston Marathon. They discuss how the attack brought out the best and worst of Twitter, and consider the unseemliness of certain punditry in the face of senseless violence. Bill argues that the obsession with whether Obama labeled the attack “terrorism” is absurd. Turning to the Gosnell murder trial, are charges from conservatives that the media ignored the story valid? Matt says the Gosnell story screams “newsworthy,” and senses a subtle media bias at work.
