Doc ... does he make it! (Spoilers!)
I don't quite get the Doc's arrest, he walks past the two cops busy on the telephone, gets into the cab and convinces the driver to drive him out of town (where most of the police blockades etc are). The cab driver tells him that they may have to stop for gas but Doc once again convinces him, "we will stop once we are out of the town...". So when we see the rest stop scene with the dancing girl, are they outside the town or still inside? Those two cops looking in through the window where did they come from?
I think if the cops didn't stop his cab before he got out of town, there's not much chance he could have been arrested later, the two cops just seem to come out of nowhere and not even sure of his identity when they arrest him. What happened to the stolen diamonds, did they recover them!
And was the Dix character supposed to be so reckless/stupid. First he pulls in the watchman and slugs him, when there was absolutely no need to pull off that stunt, which causes the accidental shooting of his partner. He could still have been the only one to escape the cops alive had he listened and gotten his bullet wound looked at by a doctor while they were hiding out.
The film tries too hard unrealistically to get the message across to viewers, the good guys always win and bad guys always lose.
