I'm inclined to believe the FBI on this occasion, although the reasoning is getting confusing ("But you've also bested my Spaniard...Surely I cannot chose the wine in front of me")
If the Antisec account is accurate (that they popped this agent's computer), then they most likely possess further evidence that they could release to corroborate their claim (The .csv file may have been the only interesting file, but presumably they copied off lots of uninteresting ones as well).
So if the FBI is lying, they have to assume that Antisec's next move would be to release more corroborating evidence (because who wouldn't be upset over being called a liar), which would then make the FBI look incredibly foolish (as well as now on record as having given false statements).
This leads me to believe that the FBI is telling the truth, and that Antisec obtained the list from somewhere else, and is just having a laugh at the FBI's expense.
Sadly, I don't think either of these groups have built up an immunity to Iocane powder.
