We must act fast! The pre-cogs have predicted a double homicide and it's going to occur in just under an hour!
Wait, wait, wait - the pre-cogs are never wrong, am I right? Cos if so, they must be predicting a crime which is going to happen, yeah?
Erm...ok, go on..?
Well, if it's going to happen, and they're never wrong, then obviously we won't get there in time to prevent the crime - or they'd have predicted us preventing the crime already!
Yeah! Yeah, you're right!
Of course I am! You can't beat philosophy of time...
