A random thought!

I've been thinking a little about something that has bothered me for quite some time now. 

I think all the unfortunate things that happened to Harry Potter during his time at Hogwarts, for example almost dying for protecting the philosopher's stone, the whole basilisk fiasco with the diary, the death of Sirius, the return of Voldemort etc, all of those things that happened when Dumbledore was still alive could have all been fixed if someone both smart and powerful (Dumbledore himself duh) had used a time turner at the right moment. 

Seriously, he could have just gone back a few hours and settled the mess down. Think about that. 

Let's take one simple example: when Harry comes back from the labyrinth carrying dead Cedric, Dumbledore should have been all 'What happened? When, where and how?' Very simple, the trophy was a portkey, and bam, he time turns to the beginning of the third task and takes the portkey himself, he would have found Pettigrew with the bundle of evil in his arms and mucus maxima bawaam, Pettigrew is tied up and the bundle is put into some sort of jail cradle. End of story. 

Of course that really would have been the end of the whole thing so kinda glad it didn't happen like that. 

I'm bored.
