im supprised,that there wasnt an attemp to kill a "rat" after they become vulnerable,when there isnt police protection anymore.everytime they dont take the opportunity,they show thatt being a rat has no consequences(besides changing the relationships).they dont have hide anymore under false names and can make media appearances.
every mobster confronted with the choice between becoming a rat or gaoing to jail.makes a calculation of costs and benefits.and that becomes more favorable for ratting,when you take away the possibility of getting killed and living under false names in hiding. even the risk,that killing him would bring unwanted attention to the mob,sould be no problem,when you see the long term benefits.
