Hardcore Pawn Owner Les is a liar!

Okay, I just watched the latest episode of Hardcore Pawn, in this episode, Les the Owner of Hardcore Pawn did a complete 180 and committed a crime. In a prior episode, he clearly states to a customer that he is now allowed to pawn or buy merchandise from anyone but the legal owner of said items. However on the Jan 11th episode, Les bought a diamond ring from a guy who told him, the ring belonged to his Aunt. The guy even calls someone who purports to be that Aunt. But how does Les know that for sure? He doesn't! What a LYING ASSHOLE he is!
