When Lefty saw the boat in the magazine...
What was the deal with that part? Lefty found that the yacht that Donnie had procured was owned by (or at least being used by) the feds. When he confronted Donnie with the pic, DOnnie just kind of brushed it off by playing dumb. But then Lefty just seemed to forget about it.
Was the indication that Lefty just didn't want to believe anything bad about the guy who was his only friend or was he convinced that it wasn't actually the same boat? Was this in the book and was it explained any more than it was in the movie?
