Perhaps Michael’s brother-in-law, Carlo, had something to do with it? Can’t see weak little Fredo even giving the order, y’know?

Now I’m interested. Like I said, I hadn’t given much thought as to “the Who of it”.

Carlo was killed in the first movie. Stangled in the front seat of a moving car with a plane ticket in his hand. He put his foot through the windshield.

He did betray the family, but it was by beating up Connie to bring Sonny running. (directly into the toll-booth machine gun trap)
