No doubt Fredo was guilty of something that enabled the Tahoe shooting
Can't see him killing the shooters so the "little help" I too reckon was opening the drapes

We also can't overlook his many lies
Have we ever come up with any other viable "little help" that is useful that is other than opening the drapes?

He had no problems with that because it was his father and older brother running the show

GF2 he's nursing a big grudge against his kid brother and is conspiring with Michael's enemies in a deadly plot because he was stepped over! by his kid brother
