Terrible examples. Noriega was a known CIA informant and asset until he was no longer useful. "The U.S. also regarded Noriega as an ally in its
War on Drugs, despite Noriega himself having amassed a personal fortune through drug trafficking operations."Basically, they used him until he was no longer useful and then put a lid on him. How hard is it really to convict a foreign national that you allowed to smuggle drugs and weapons under your own tutelage. Real tough case.
Gotti was a known mobster for over a decade this was after the 5 families trial headed by Ruddi Giuliani. Blueprint was laid out and snitches were in place. By that standard Giuliani is an absolute A-star level prosecutor when he put away 5 families and essentially created RICO approach to trying mobsters.
I don't see any truly distinguishing or pioneering in Mueller's work. His brightest moment was standing up to Bush when it came to surveillance, but since then we found thanks to Snownden that the government still found the way to collect all the info they wanted.
