only one thing I don't understand [SPOILERS]
WARNING SPOILERS!!!
near the end, after Dunn had Tyler beat Rick up to get information, why did Rick walk to the girl? It's the one thing that bugs me about this movie. I've always LOVED watching it (I really like Brian De Palma's movies and Nicholas Cage is fantastic, everyone in it is fantastic), but I've never understood why Rick would risk going to the girl. Doesn't he know Dunn might follow him? It seemed like a coincidence to me that the police van showed up when it did.
The only possible explanation I can come up with is that after Rick left the girl alone he called some cop buddies and told them to come get her, but if that's the case he still wouldn't have to risk showing Dunn where she was hidden.
