I'm thinking the Don smelled something with the Tataglia thing. I think the reason Vito said no had more to do with dealing with Sollozo and not trusting him rather than just being against drugs.



Long as I remember The rain been coming down.
Clouds of Mystery pouring Confusion on the ground.
Good men through the ages, Trying to find the sun;
And I wonder, Still I wonder, Who'll stop the rain.
