Oh, but it is clear that *Hermione* doesn't understand. She *does* 
need to go by strict guidelines - and one is NOT to attempt to change 
the past. It *is* a theoretical possibility, but I doubt anyone 
CAN/WILL do it in practice.

And of course Ministry would control it! What *don't* they try to 
control? Particularly a device that would provide an iron-clad alibi 
to any wanna-be criminal... say someone with the help of timeturner 
commits murder and uses TT to have an alibi by er - having a party 
with members of Wizengamot... (who MIGHT consider the TT-possibility, 
but think of Muggle-courts and make the alibi-providers be judges or 
cops...)
