this was a municipal building that also included the police office. and since the police were off duty, the door would have been locked anyway. my guess is that she went into the building, not the actual police part. but the story is sexier if you say she ran into the police building and found it empty. just more media spin.
Just words. We all play with them, don't we? I was wondering why the door was unlocked too. It probably wouldn't have made any difference though. She needed a gun too. I don't jump on the wagon blaming the police though. They had things covered. It could just as easily have been an older, closed station.
