Prosecuting the Boston Bombing Suspect

The suspect in the Boston Marathon bombing has been charged with using weapons of mass destruction, a charge which can carry the death penalty. We hear about his condition and how he's being treated by federal authorities. Did the FBI fail to follow up on what it knew about his radicalized older brother? What's the impact on American Muslims, now and in the future? Also, the history of Earth Day.
