It was suspenseful, Michael watching like a hawk, the Military Police marching in wondering whether they were his Military 'protection'!

As regards Michael “still hanging around” even after Michael saw the Military Police, they were marching away from Michael So, Michael must have twigged something more serious than his murder assignment was happening

My queries please and somewhat confusing take!
  • Military Police informed Batista of his untenable position due to the rebels taking over
  • Whilst no one could have known of Roth's stroke, the Military went to Roth's hotel to check / inform Roth, Batista's old friend and associate of Batista's resignation due to Roth's no show at the New Year reception
  • Military must have found out Roth was in the hospital and took care of Batista's old friend and associate Roth
  • No brainer the Military or plain clothes personnel would take Michael away in full view of all the guests
  • Fredo broke free of Michael's “You broke my heart” embrace and seemingly walked quickly out of the Palace
  • Michael made his smart lone exit down the Presidential Palace steps
  • The assassins after “Batista resigned were more worried about saving their own asses than about nailing Michael's” So under the same circumstances, why would the Military Police worry about Roth?
