Dreamed I was a detective.

I was some sort of law enforcement officer. I had a weapon but no bullets. I was shot at. I killed the suspect with their own gun. I was in shock. I shouldn't have been there in the first place, but he was the one we were looking for. I was lucky that I got off. It was murder, even if he was a serial rapist. I joined a therapy group; Dirty Harry was in my group. I'm still shaking from the experience and not sure where this is. Seems like New York. Elevated train, but not sure. Summertime.
