That is an interesting analysis waynethegame. What is a mock execution?

Personally,maybe because what happened to Carlo I always thought that Michael knew he was going to kill Fredo when he got back from Cuba. I always felt that he implied this when he said to Tom to get in touch with Fredo and tell him everything was all right. I thought he wanted to sweet talk him to come back so he could kill him anytime. I even had the feeling that Tom understood this too.
