Fair points, it would be very impressive if he could pull it all off, but I think Dark Harry could manage to do it with some luck.
*For the wand I was thinking of something like pulling it out and then pushing someone into Lord Jugson and dropping it at his feet. He could properly time it so that 1st harry pulls it out and runs then 2cd harry immediately pushes either Jugson or someone into Jugson and drops the wand at his feet. Even if Jugson suspects something what can he prove?
*If Quirrel had returned to the School already Harry would know, if he is still in interrogation it says specifically that Quirrel is in the magical law department, which is in the ministry which is in the Wizengamot. It wouldn't be hard for Harry to know/learn thats where Quirrel was. He would just have to find his way there. Snape is presumably back in Hogwarts as a teacher. He would just have to take the Floo network back to Hogwarts. He doesn't have to take another student he is just has to make sure they show up on time.
*Dumbledore doesn't have to do it, Harry could get Snape or Quirrel to do it. Probably conspicuously absent Quirrel.
*Jugson could easily have an alibi but its hard to prove he didn't just false memory charm the people for the alibi too.
EDIT: New discussion thread here.
This is a new thread to discuss Eliezer Yudkowsky's Harry Potter and the Methods of Rationality and anything related to it. With two chapters recently the previous thread has very quickly reached 500 comments. The latest chapter as of 17th March 2012 is Ch. 79.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author's Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: one, two, three, four, five, six, seven, eight, nine, ten.
As a reminder, it's often useful to start your comment by indicating which chapter you are commenting on.
Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:
