Plot hole: Why do all the Germans abandon the cable car control room after the alarm has been sounded?

Plot hole: The movie is based on one huge plot hole: if it wasn't for the "professional" hitman's sloppy work, Bullitt and his team wouldn't have been needed for much. The hitman enters the hotel room, wounds the policeman, then shoots the target with one shotgun blast to his upper left shoulder area. Any hitman worth his fee knows that this is not likely to be an immediately fatal wound. The hitman had a pump shotgun and should have finished the job right then and there. Surely he had more than two shells. Instead, he sees the target is slumped unconscious, then leaves the hotel room without checking to see that his victim really is dead. Nothing seems to be immediately threatening the hit team, though. The hitman spends the rest of his life trying to finish his job and pays the ultimate price for being lazy.
