Plot question
Most of the discussion for this good, but not as good as The French Connection, movie appears to be centered on the fantastic car chase. But I have a very simple question about the plot: How did Buddy figure out his informant was working with the kidnappers? I was expecting at least a partial explanation at the end, but all Scheider did was mention "the blond guy," and the informant cracked. What was going on there?
What's the Spanish for drunken bum?
