BTW, I loved the film and gave it a 9/10, but this clarification may raise it to a 9.5 Why was that cop left in the
interrogation room with the Joker, knowing that there was broken glass in there and that most of his fellow cops were going to be absent (since they were going after Rachel and Dent)??? IMO, that is the only legitmate loose end/plot hole that hasn't been explained yet. Anyone...
