Ways Gal could have gotten out of it.....
OK I was just watching this movie again. Gal now lives in Spain, far away from his old criminal gang. Why couldn't he have faked an injury to get out of it? I can understand him not wanting to be away when Don showed up because with Don's persistence he probably would have showed up another time. I'm thinking if he had just walked around slowly and painfully with a cane or walker he probably would have been left alone.
Besides, and I've seen this argument here before, why exactly does Don need Gal for this job anyways? There was like a dozen guys working on this using pneumatic drills. That doesn't require too much expertise. Instead of 12 just use 11 guys! It probably would have been done OK.....
