Setting a legal precedent, a German court has upheld a conviction of a former SS guard whom the court said was part of the Nazi 'machinery of death.'

94-year-old former SS sergeant Oskar Groening, who served at the Auschwitz death camp, was convicted Wednesday on 300,000 counts of accessory to murder and given a four-year sentence.

The wheels of justice turn slowly, but a 93-year-old former SS guard is finally being brought to justice.
