Yeah good point.If you look at the Castellano hit it was pretty elaborate.They stationed this guy here,these backup shooters here,crash car there and on and on.A very strategic hit.Then just pulling up blasting at Gigante (the real head of the commission) in his own club.But if you think about it how else could you kill The Chin.He never went to Sparks or Tomassos.He never went more than a mile down the road his whole life.You would almost have to pull up on him and start shooting.It would really be a suicide mission.Like you said he always had killers around him.If you were to pull up at the triangle they may have gotten Gigante.But just like Columbo the men around Chin would surely have killed the hit team.He didnt even take money from his capos much less tell them where he would be going at a certain time.He only spoke with Baldy Dom,mangano,Mana just a few.So no capo could betray him like Deccico did Castellano.So you can't ambush.No way to pull it off the guy never went nowhere
