Great point! Do you think Barzini sent Solozzo to Tattaglia because he had made his living before from prostitution? This way he would look like he was just a guy that came up through the ranks in the Tattaglia family and was looking to start an organized narcotics racket? Also do you think Tattaglia was aware of the fact he was being used as a stooge by Barzini, which would be easy due to the fact Tattaglia would be blinded by the millions he was promised to make.
