Just a couple of points. Yes the FBI has downsized somewhat and their big focus is now terrorism,so don't think for a minute that they have forgotten about organized crime. They still monitor it.
The organized criminals aren't throwing dead bodies all over the street as in the past- apparently they have learned something. You get another guy like Gotti in there who struts around rubbing it in their faces, the FBI will go into action again. If we get a Republican in the White House, I believe they will spend more money on law enforcement and maybe loosen some of the restrictions now face.
