Not the same
It's one thing to find that piece of enemy scum, place your crosshairs over them and blow their brains out in a game. It's quite another to do it in real life where one knows someone is actually going to get hurt/killed. And the kind of person who would willingly do it IRL is so far gone, I rather doubt the game has much influence.
Are they considering "Risk" a breach of human rights as well? Chess?
This is just a piece of PR grabbing straight from the PeTA game book and it is shameful for an institution such as the Red Cross to stoop so low.
