The FBI, as MPAA's minions, should be the ones paying it. Either their "confiscate" the data or they do not. If they do, they have the responsibility to keep it up, if they do not, they should have to give it back to its "owner".
Unwitting puppets perhaps, but I doubt the people of the FBI want very much to be dealing with copyright drama. That's like fixing bugs in form code to them. It must feel like a complete waste of their time and talent.
