Actually I have been on the other side of this one. When I got divorced my ex locked me out of the house with all he games inside. Despite the court order not to remove anything she started selling games off. I reported it to cops and court but they really did not care in the least. They told me it was a civil issue as they belonged to her as well and it would come out in settlement. Eventually I was able to get in and take enough to get 50% of value of what was there. Bottom line is that this is between them and nothing they would be able to do with you. I would guess he is just upset at having stuff sold out from under him - I know I was but didn't do anything like he has. Divorce makes people do some pretty silly stuff.
