"Also, look at the restrictions on time travel.  You can't change
things.  Granted, Hermione and Harry did.  But, would the results

This is simple (I think). When Harry and Cedric left nobody knew 
where they were going. By the time they got back, and the whole 
graveyard scene had transpired, it was to late. If someone had gone 
back to stop them then they would never have gone and so no one would 
have known that there was any danger, and therefore not stopped them.

Argh! I guess that I should probably try to go back in time and 
change this message. It doesn't make much sense eh?
