A FEW years ago, I visited Auschwitz and recently I watched a documentary on Anne Frank, whose house I’m going to visit in Amsterdam later this year.

Unfortunately these sort of things could and have to a scale happened again. Nigeria 1968, Cambodia 1976, Yugoslavia and Kosovo 1993 and now Syria.

Look at the sort of ghastly crimes you keep reading about in the papers and some of the sort who are in our prisons.

It is our duty as civilised human beings to make sure that this sort of thing never happens again, and to remember that those who do nothing about stopping evil when it happens are as bad as those who commit it.
