Weird Crime Story Idea

While I was waiting for a pizza tonight, I thought of this interesting crime story. I call the concept "50-State Cop Killer". It's about a guy who goes around shooting 1 cop in every state, told as a first person retrospective by the killer. He's facing down the 50th man during the story. At first he just sniped at them, then he decides to make each killing harder by trying to find specific scenarios, like cops who are bad, or cops that fall into his traps. He begins leaving clues as well, trying to increase the degree of difficulty. Of course when there are only a couple of states left, things get really dicey because the net is closing around him and the police are extra vigilant.

Of course this all starts out with some kind of grudge. Perhaps a cop killed his family, or he has police in his family who wronged him. This all leads back to the last killing, his final act, where he intends to culminate his wrongful spree. The last victim is of course somehow tied to him or his past, and is a pretty good guy. This victim is essentially the hero of the story, although he has his share of skeletons in the closet.

I haven't written much if anything about crime or cops or anything like that. I'll need to think through this idea some time and see where it goes...
