[I]n Scotland, where the Holocaust is not on the national curriculum, many teenagers have never heard of Auschwitz, never mind of the cold, calculating extermination of men, women and children which took place there.

And many believe this murder on a terrible scale could easily happen again unless the lessons from Auschwitz are finally learned.

Which is why the Holocaust Education Trust decided to take a group of Scottish school pupils to the concentration camp.

The purpose was to teach the youngsters how seemingly harmless prejudices can develop into mass dehumanisation and the eventual extermination of millions.
