Sorry I was not clear I was referring to Vito leaving himself wide open for his hit such an easy target with just “And Fredo -- well -- Fredo was -- well --†and buying fruit alone out in the open especially if it was a regular thing ie: easy tracking of Vito's movements - sitting duck! [Fredo waits in the car!]
Sure thing Turnbull trying to find out what Sollozzo's got under his fingernails was business [sending Luca to do so was irrational!]
Sollozzo's only “move against him [Vito] to force him[?] or Sonny to reverse his decision not to accept Sol's deal†would have to be the murder of Vito for which Vito was so ill-prepared, underestimating Sollozzo and never saw it coming
