I caught a short piece of GF1 on TV today. The scene where Kay brings the letter to Tom to give to Michael, Tom replies with something to the effect: "If I accept this letter, they could prove in a court of law that I knew of his whereabouts...".
Was Tom being sarcastic, or was he really concerned about what the court would think? Unless Kay knew about the Sollozzo murder, it seems like her response should have been: "why do you care what the court thinks?".
It alway seemed like a peculiar line to me.
