INT. ROTH'S SUITE IN HAVANA - MED. CLOSE VIEW ON ROTH - DAY

His wizened face, pale. Right now, though, his eyes have a
sparkle as he watches three million dollars in cold cash
being counted on a card table in front of him.
A deleted scene from the script...

His brother Sam is present, and the sandy-haired Courier, a
little nervous; the one who had left from the Tropicana with
the Corleone skim-money. Also Johnny Ola. The money is
evidently all there; Roth picks up a packet; probably a
hundred thousand dollars, and throws it over to the Courier.

ROTH
Make it fast; I don't want to
chance him being seen.


COURIER
(frightened)
What about the arrangements? How
can I be sure about the arrangements?

OLA
Relax. You're under our protection;
the Corleone family will never find
you.

Ola leads the Courier to the adjoining room where two
smartly dressed Military (Cuban) Police are standing, and a
civilian. The Courier sees them, looks back to Ola. One of
the police steps forward, placing the Courier under arrest;
handcuffing him.

COURIER
Hey, what's this?

The other takes the packet of money, and hands it to the
civilian, who places it in the briefcase he carries. The
other officer kneels down and fastens leg manacles.

COURIER
The arrangements... YOU BASTARDS!
What...

The Captain strikes him expertly across the side of his head
with his pistol.

Ola closes the door on this scene.


So Roth robbed the courier in Havana. Michael sent the next multi-million dollar shipment with
Fredo, someone he trusted at that point. I assume now that Roth new that Michael would send
the next shipment with Fredo, and it paid off when Fredo betrayed Michael and saved Roth's life.
