How the government's punishing of the exposure of official wrongdoing can linger for years
Children who survived last month's shooting rampage at Connecticut's Sandy Hook Elementary School have recorded a version of "Over the Rainbow" to raise money for charity.

With security stepped up and families still on edge in Newtown, students began returning to school Tuesday for the first time since last week's massacre, bringing a return of familiar routines - at least, for some - to a grief-stricken town as it buries 20 of its children.

In the window of a local deli, the mother of a Sandy Hook Elementary School student has left a message for this grieving town. Mourning will continue for weeks, months, even years, but focus is turning increasingly to larger issues surrounding Friday's massacre.
