Kelly's good. So was Bratton. And that other guy, can't remember his name, who never made PC, but knew technology and was a good cop. Actually, I think he ended up in NO, if memory serves.
I see the NYPD having a couple of landmarks in the 20th century. Knapp/Serpico was one, and then the Kelly/Bratton years was another.
That would be Jack Maple, who, I believe, passed away not too long ago.
