Deirdre:
Or better yet, why hasn't Dumbledore or someone else gone back and killed
pre-powerful Voldemort? 

James:
The mechanic they work proberbly impose limitations on their use that have
not been mentioned. A couple of ideas I've had are:

a)We know time in the wizarding world can be stored (remember the bell jar
the DE fell into). The turners may contain a small store of time that
'fuels' the time travel. The turners only have a finite store and the source
may be limited (I can imagine a huge machine in the ministry that churns out
a few minutes a day, slowly stockpileing time that is rationed out where
needed).

b)The time turners may not be able to transport back in time past their own
creation. Modern physics can (on paper at least, it's all still theory) use
worm holes to travel back in time, but not past the creation point of the
worm hole, something similer may be at work with the turners. It's possible
that the time turners are only a recent invention and none exist that could
be used to go back that far.
