OK, if convicting the FBI is the topic, let’s at least throw in
a “close to home” (Boston/Mass) case:
“John “Zip” Connolly is a former FBI agent, currently in federal prison
for racketeering and obstruction of justice stemming from his relationship
with Whitey Bulger, Steve Flemmi, and the Winter Hill Gang.”
http://en.wikipedia.org/wiki/John_Connolly_%28FBI%29
But it's not just close to their Boston-area home. Connolly and Whitey Bulger and other Winter Hill mob crew members were responsible, among other things, for organized crime murders in Miami, Tulsa, Oklahoma and Tennessee/Mississippi.
Indeed, one of the killers who tried to murder Tennessee *Walking Tall* Sheriff Buford Pusser on 12 August 1968 but instead killed his wife Pauline instead was Boston hit man Carmine Raymond *Ray Gags* Gagliardi, formerly of the FBI's Ten Most Wanted Fugitives list.
Amusingly, when the Feebies caight up with Ray Gags, it was during a Christmastime visit to his mudder's house, though it's now a bit unclear if his brudder, a local cop, was at hoime at the time or not, nor if he was the one who tipped of the feds that mom had a visitor, or had been protecting him.
Likewise, Steve *The Rifleman* Flemmi's brother Mikey was among the Boys in Blue of the Boston Police Department, having worked his way up the rankls from beat cop to crime scene photog. Accordingly, the courts granted him an earlier release date in 2011, which might give him a chance to hide out from anyone who still wants him kept quiet, whether about the other feds and BPD cops in on the gang's activities, and of course the elusive Whitey is still wanted, and is either hiding out where he's well-protected, or his remains are well-hidden.
