I think that the colombos hierarchy prefer a boss on the streets that an another boss in prison because the family can be rebuilted only a boss on the street,for sure allie boy will be the official boss and will receive some money from the his parents but nothing more.
The last commission meeting was in 2000 but anyway the colombos have rackets with the other families so the new boss should ask the other family rapresentatives for be to be recognized as new boss.
