Frankly, it depends on the situation.
We have situations--and perhaps we could take the O'Connor report as an example--where there is a seizure of hard drives. Because we're not capable of processing it, we may give a copy on CD of that hard drive to our allied services to assist us in the processing. That could contain a huge amount of information. On the other hand, it may simply be a request such as “What do you know about this person?”
Again--I'm speaking for CSIS--we would rarely answer a question that was not put into the context of why the question is being asked and for what purpose.
