How did the rival crews suss out that Tommy was responsible for Billy Batts' death? In real life they didn't even have the squabble they had in the film, Batt's just asked Tommy if he still shined shoes. Regardless, when Batts was killed, no one else was around but an Italian couple...aside from guesswork, the couple informing seems to be the only way I can think of...anyone else know how they found out?
