What do you mean? Just because something is a prohibited transaction doesn't mean there is a magical fairly that ensures you don't. I'm sure you are aware that the audit-rate for wealthy individuals is (and was) significantly lower than other income brackets. There is no magical automated system that is going to catch and flag a not-arms-length transaction, and I'm sure he (well, his legal team) is sitting around saying "well it's a shame this wasn't caught at the time, you know, statute of limitations and such".
