I’ll be Jussie knows exactly what those two told the police.
They probably blurted out the truth. These are foreigners dealing with cops who are now impatient and ready to be done with it all.
Quite possibly texts, e-mails, phone logs, banking records... If Smollett did set the whole thing up, these brothers probably gave CPD everything in return for no jail time.
It's also possible the guys refused to beat Jussie and backed out of the 'deal'. That would explain why Smollett had no injuries beyond a little scratch.
