Well the son is dead, nothing can be done after the jury mistakenly acquitted Simpson. But did OJ really shirk obligations? AFAIK the whole reason he even wrote “IF I DID IT” was to try to pay them what was owed, and they accepted that deal.
The man’s whole estate appears to be worth about 3 Million USD, and he’s survived by four children. Maybe it’s time we put the dead to rest.
