I don't see Club Fed as any deterrent value. Gitmo or Leavenworth perhaps but Club Fed is too much of an 'oh well' moment for these traitors. <<< notice Blackbirds use of the plural, traitors. We are rife with them. Try them then kill them deader than hell. Maybe hold off on the kill shot until after you have wiped out all of their ill gotten gains, show them how you have expanded your investigation into all of their family and close associations. Make them watch their shame being cleansed from society. Throat punches until they suffocate. Maybe I'm just a little more hardcore than most. Medieval even. <<< Alas, no animals were harmed in my version Caesar! ref:sack cloth, bobcat, water. That's me softening my tone.
You could do a live feed of Mallory and Lonely Bubba to show the state department weenies. The problem is that half the state department would volunteer to trade places!!
Execution would be more of a deterrent.
