Fossil: "We need to forgive and forget..." That's easily said, but not, presumably, by the family involved. Surely only they can decide to forgive, I doubt whether they can ever forget.
It seems to me that this attitude of trying to keep things steady and looking to the future, turning a blind eye to the atrocities committed, is rather placatory and not very edifying. Like giving a tiger a nice piece of meat in the hope that it won't bite you. These people (on both sides) who killed and maimed are evil criminals, and by 'forgetting' what they did we almost condone it. I feel that the Law must take its course. It's no good just hoping they'll be sensible and peaceable from now on. They probably won't. But by pursuing them in the courts, at least one is maintaining the Law of the land. No-one is above that, not even powerful terrorists.
