Question: How is Martin able to freely travel at the end? I get that he has fake passports, but given that he admitted to the German police that he is an assassin, and that he is the one who planted the bomb in the hotel, wouldn't they have shared his picture with Interpol, regardless of the fact that he prevented the deaths of Bressler and the Saudi prince?
Question: What (if any) is the significance of the "OZ" graffiti that pops up throughout the film? It became quite distracting as I thought it would pay off at the end of the film.
Question: Why do they simply kill dozens of people in the movie, but with him it has to be something long and drawn out, like poison in the hospital or drugs in the parking garage?
Question: Since Neeson is no longer in the assassin corps at the end of the movie, how does he so ably secure fake passports?
