The killing of Michael Brown has tapped into something bigger than Michael Brown.
Brown was the unarmed 18-year-old black man who was shot to death Saturday by a policeman in Ferguson, Mo. There are conflicting accounts of the events that led to the shooting. There is an investigation by local authorities as well as one by federal authorities. There are grieving parents and a seething community. There are swarms of lawyers and hordes of reporters. There has been unrest. The president has appealed for reflection and healing.
