I see no points of those hearing, evidence, and apologies, except political advantage. When it's done, it's done. You can either choose bloody revenge or walk on your life. You can't reverse the time or wipe out the agony now. Just imagine how many corpses were built up during the past 50-100 years, butchered by whoever is responsible. Did we hear any apologies from them? Shall we demand regret and condolence from all of the parties? Or maybe we shall butcher them back?
As far as I understand the whole story, it is a show now, played by the politicians, watched by the general public, and led to nowhere.
