MIT runs Lincoln Lab which is a think tank / R&D facility for the military. You have to pass through an armed checkpoint to get to the the complex located on an AF base. I would consider that node compromised already.
Counterintuitively sometimes the best protection is to operate under another agency. That makes moving against Tor a battle of internal politics rather than a legal battle.
'The government' rarely has uniform views on something as complex as Tor.
Stop.
