Holocaust denier Irving is jailed
Note, the fear that deniers could gain the upper hand led an SS camp guard, Oskar Groening, to break a lifetime of silence earlier this year in a BBC documentary, Auschwitz: The Nazis and the Final Solution.
"I saw the gas chambers. I saw the crematoria. I saw the open fires. I was on the ramp when the selections [for the gas chambers] took place," said Mr Groening, now in his 80s. "I would like you to believe these atrocities happened - because I was there."
