This guy is fucking stone cold lol. Look at the glee on his face when he talks about driving a stake through the vampire's heart @40.30mins onwards:

It's an old documentary (late 1980s I think) about the take-down of Gotti and the other 5 families in New York. They interview some of the key players, including the AG himself.
I haven't watched the whole thing but I found another clip of him @1.42mins as well.
I don't think Nadler and his crew even know what they are in for with this guy. He's a literal machine of justice that dismantled the entire mob (along with Rudy). They're out of their fucking league with this guy........
