Eric Frein, the would-be revolutionary who shot two Pennsylvania troopers, one fatally, in a late-night attack at their barracks, was sentenced to death late Wednesday. The jury's decision that Frein should die by lethal injection brought a shouted "yes!" from a gallery that included high-ranking state police brass, the slain officer's mother and the trooper who suffered debilitating injuries after Frein shot him with a high-powered rifle.
