No sweat the pigs will just coerce a co-defendent to cooperate. They'll promise him/her immunity if they just testify against you.
It's how they got Gotti. They let Sammy "the bull****ter" continue to sell ecstacyto 16 year old girls with fake id's at the Limelight and granted him immunity even though he killed more people than Gotti.
But Gotti was the high publicity target. Some POS in the FBI made a name for himself, all the while pulling his pants down and let Sammy the bull****ter **** him up the ass.
