he should have been whacked in like the 3rd episode of the series because he and his buddy hijacked junior's truck after they had been specifically told not to.

tony protected him because he was trying to assert his dominance over junior in their power play for the crown.

season 2 as mentioned he misses the banquet with the guys from italy because he's stoned on junk in his hotel room,.. he also put his hands on adrianna which caused richie to come very close to having him whacked and probably would have at some point if he hadn't try to make a move on tony

season 3 he's doing junk as a made guy.

There were a million incidents with that guy
