In both the novel and the film, Vito tells Solozzo that he can't go along with his deal because drugs would jeopardize the police and political protection he needed for his gambling and union interests. But in the novel, Vito seems to invoke some "moral" objections to drugs:

--As he's about to leave his office for Connie's wedding,Tom says he can't hold off the Solozzo meeting much longer. Vito replies, "What he will propose will be an infamita."

--After Tom finishes briefing Sonny and Vito about the upcoming Solozzo meeting, Vito tells him, "Do you have in your notes that Solozzo made his living before the war from prostitution? As the Tattaglias do now? Write that down before you forget." Tom is stung, but attributes it to the fact that Vito was "notoriously straighlaced in matters of sex." (How Tom knew that could be the topic of another thread. )

Do you think that Vito was serious about those objections, and that they had any weight in his decision not to go with Sol's proposition? If not, why did he raise them?
