When I was about 10 or 11, my mother insisted I should watch footage of the Nazi concentration camps, filmed after liberation, when it appeared on television. She didn’t force me to watch, but said that everyone should if they could.
Horrifying as that footage was, of emaciated figures, some dead, some alive, and some that couldn’t be said to be either with any certainty, I think my mum was right. We should all know what the statistics bandied around after such atrocities actually mean, and we should all be horrified, and condemn the perpetrators.
The idea is to try and stop such things happening again, but of course they will, and of course they have, time and again. We should still try though, so please, if you can, watch this video.
