"K":

According to JKR, time travel *can* alter the past. I'm not a big 
fan of time travel but it is hard to dismiss Hermione's comments in 
PoA.

'Hermione,' said Harry suddenly, 'what if we-we just run in there,
and grab Pettigrew-'

'No!' said Hermione in a terrified whisper. 'Don't you understand?
We're breaking one of the most important wizarding laws! Nobody's

'Hermione!' said Harry suddenly. 'We've got to move!'

Hermione looked up. Her expression was suspicious.

'I'm not going to try and interfere,' said Harry quickly.

'Exactly! You wouldn't understand, you might even attack yourself!
Don't you see? Professor McGonagall told me what awful things have
happened when wizards have meddled with time...loads of them ended
up killing their past or future selves by mistake!'
