One of the big rules of the mafia families is to never “hit” a federal agent, prosecutor, or judge. They knew that if they ever did so, the the gig was up, with the U.S. government coming down upon them with all the force that it could muster. The mobsters knew this and so did the feds. It was part of the game.
that didn’t stop the pittsburgh mob from trying to take out a prosecutor in youngstown, ohio. the guy was shot and barely survived. but the end result was, the feds came crashin down on that party and the head of the pittsburgh mob got sent away for a long time..
