Have to stand by what I posted in 2015. If I could I would push this higher. I've since decided that instead of calling the old fraud Dumbles I'll call him Fumblemort. Simply because he totally fumbles all his dealings with Harry and he's even more of a Dark Lord then Voldemort is! Voldemort will torture but he'll usually kill you fairly quickly. Fumblemort on the other hand will just keep torturing you till he finally has no further use for you. I'm convinced he deliberately allowed the Potter family to be killed and the Longbottoms tortured into insanity as it fit his plans. Though, I've read other stories that state it was because both families wouldn't follow his rule of not killing the Death Eaters during fights. They became expendable because of it. The same applies to Molly's brothers. Fumblemort wanted the Death Eaters to live as they were from the old families. Meaning very Ancient magic that he didn't want to die out. Though, in those stories it's never stated nor hinted at whether or not the Potter or Longbottom families fell into the same category.
One of the things in HP stories that really bothers me is that McGonagall never bothers to stay with Harry whenever he goes to Fumblemorts' office. She's his Head Of House but never acts on that duty to him. But Snape's always there even though Harry not in his House. And the worst part is that NO ONE on the staff stands up for Harry! I really don't see why he never went to Gringotts to check on his vault(s) or if his parent had a WILL. Especially after fourth year! Give his fat, greedy uncle a couple of gold coins to drop him at the Leaky Caldron and go to the bank. But then Harry wouldn't be the doormat that JKR wrote him as if he did.
