The fucking fbi. In one of the A&E documentaries, they say they knocked out the Dobermans with a steak and put the bugs in. Another time they say that they made something go wrong with cable and posed as a cable guy with a bodyguard (maybe Bilotti) hovering over them while they pretended to fix the cable but were really placing a bug. Bunch of liars. After all of that time and money they get him on nothing and there is still a Gambino family.
Happen to have links to those?
