You expect OJ Simpson not to be petty when after getting away with the murder of 2 people?! I sure dont.
The lawyer is just being a lawyer, i also don’t expect him to not be a lawyer.
You dont appoint a lawyer as your executor and not expect them to do lawyer things with legal documents.
The US judicial system is fucked as much as anyone elses but the rich routinely weaponize the court systems there for any number of reasons. OJ doing absolutely everything he can think of to protect his ego is pretty fucking on brand
