Perhaps I'm overlooking something BIG, but what exactly did Fredo do? I can only assume because he says "I swear I didn't know it was a hit" that he is telling the truth. So what exactly did he do??

And who guns down the two gunmen that were found in the ditch? It had to be someone that knew that the hit failed, and supposedly Fredo didn't know about the hit. Also, I can't picture Fredo gunning anyone down.

Do you think he was lying and that he knew it was going to be a hit and that he wanted to take control of the family?

After years and years of being a Godfather fanatic, I never took the time to analyze it until I joined this BB. I just assumed that Fredo was duped into opening Mike up to be killed unknowingly, but that seems unlikely now...
