Looks like OJ was getting kickbacks on memorabilia sales by these dealers and wasn’t reporting the income to the IRS nor the families of his murder victims.
And it also looks like OJ got greedy and wanted a bigger kickback and decided to rip off the dealer in the hotel.
I think this is exactly right. I'd say he gave the guys the stuff to sell, reported it stolen etc. He should do time for violating the court order, tax evasion, conspiracy to do each, conspiracy to armed robbery just to name a few...
