Heres an fbi report from anonymous FBI agent that visited Lucky on board the Laura Keene before leaving the docks.Its showing the respect other gangsters had for Luciano:

“Upon my arrival there, I saw a gang or mob of 60 to 80 men and about 20 to 30 cars. I have no idea to their identity or their purpose for being on hand.When the ship left the pier at 8:50 a.m., a launch followed the ship for three miles."

The agent guessed it was members of the press trying to get one final shot of Luciano. The agent left the ship at 2:00 p.m. when he caught a ride on a fishing ship returning to the Brooklyn docks.

Maybe the stories about Lucky getting envelops in Havana are true...who knows
