Sea Change replies to this turn of the thread, and quotes the above
just to let you know where I stepped in:

We know that Veritaserum exists and it's the only truthtelling potion
that isn't poisonous, but do we know from canon that there's no
counterpotion or antivenin that you can take ahead of time that
counteracts it or messes with the results?  

Perhaps Imperio works like a computer program.  That is to say you can
direct your subject to tell the truth, but then you would have to know
the address of the library called 'truth' in order to call up that
subroutine. Failing that, you could tell the cursed person to call up
*your* version of the truth, in order to deceive others when you are
not around and they are talking to others, but this is not directly
helpful to you, especially if it wipes out a portion of their hard
drive that actually has the 'truth' library (i.e., their brain).
