Jeff LichtmanAdam, no targets could have received subpoenas for their testimony -- because then they could simply assert the 5th, get immunity, and have their sins washed away. My guess is that any target that received a subpoena was for documents only. Anyone who received a subpoena for their testimony is probably just a witness for the Grand Jury.
And, of course, you're right: the reason why the subpoenas were served at the National is because the FBI/Postal Inspector was basically shooting fish in a barrel by having everyone under one roof.
