In The Godfather, when Tessio learns his fate, he says :
Tell Mike it was only business... I always liked him.
Then a bodyguard reaches his jacket pocket to take Tessio's gun.
It looks like Tessio was considering reaching his gun at this very moment. Was he seriously considering taking out all the goons and escaping? He seem to have accepted his fate, then he had this slight arm movement that bothers me.
Details from the book are welcome.
