I agree with Loote and I don't want to completely rule out the possibility that Dipendra did it. But, all the evidences try to tell the story other ways. however, we don't have any proofs so can't blame anyone. However, this is going to be in the history and our forthcoming generation is going to believe what they read on the history books. It is kinda disturbing to me that the fact is not going to be the history but a guess. I wish the government would form a panel to investigate. Since, KG has been cut off with his superior powers, investigation team could somehow lighten the truth. My wishful thinking!
