Lets assume Gotti had a genious IQ. Would that have made a difference? No.
He would of ended up the same way. Lets say he never talked and wasnt high profile? He still would of ended up in prison for life and there would of been another rat that identified each and every capo.
Look how low profile bin laden was and we found him.
Once the government targets you, its all over.
Was Gigante smart?? What kind of life did he have?? A shitty one. At least gotti enjoyed life. Gigante lived the life of a prisoner before he ever went to prison.
