During the Anbu backstory of Kakashi, why didn't he notify the Third Hokage about Danzo's plan for Orochimaru to flee? Also, why weren't the Uchiha clan asked to stop the Nine Tails during the Konoha attack and why did the Third Hokage not imprison Danzo for keeping Yamato's existence a secret? Finally, why did Danzo allow the Nine Tails to attack Konoha if he wants to protect the Leaf above all else?
