Hi Sasha,
Sorry I didn't see it, I'd have watched if I'd known it was on, however, I hope that doesn't mean my opinion on the matter is any less relevant.
Bravo to the mother for having the courage to open the coffin to the nation. I don't have a problem with that per se, particularly since we see death and murder pretty much every night on the news.
Do I think it will make any difference? No, not really. The people with the mentality of carrying a knife around with a view to using it on someone (why else would they be carrying a knife?) are people who lack compassion and consideration for others and are generally nothing more than thugs. I honestly can't see them sitting infront of the TV thinking "Oh, if that's what it looks like to stab someone, I'll just not do it", because it was never in their thought process anyway.
Although the 2 are very different, I kind of liken it to smoking.....the manufacturers are putting pictures on the packet of cigarette's of the damage that smoking does, but that doesn't stop me from doing it.
However, if she has got through to one person by showing us the damage, then it's got to have been worth it.
