Law enforcement websites?

Hi I am an MP stationed in Germany, when i was stationed stateside we had a intelligence specialist who told us about some websites specifically made only for law enforcement officers that had important information and updates and criminal info and such for police they want to know and etc... I never took much interest in it, but now I am trying to take a bigger role in our department here so If anyone could give me some of the links to them so i can register and such i would appreciate it.
