I might be wrong here, but I don't think ignorance is a defence here. He would be expected to carry out due diligence before buying the club.It's not quite the same though. It's more like finding out your partner committed murders and grassing them up.
Boehly wasn't there committing the crimes and, possibly wouldn’t have purchased them if he knew what he'd find after the deal went through.
I've never heard of any serious businessman buying a business without a full appraisal of the accounts. If they'd done a proper job, then surely they'd have seen the anomalies in payments?
How dumb do you have to be to buy the club then, shortly afterwards, find those anomalies? We're talking about a multi Billion pound purchase here, you'd normally get forensic accountants all over the books for weeks before signing the contract.
I just cannot see how Boehly and his mob didn't know about them before he bought the club.
