Your probation officer was wrong. A lot of people employed in law enforcement do not fully understand the law, but like doctors, feel compelled to speak with authority based upon assumptions. You are under no obligation to answer any of his questions, especially pro-actively. A probation officer probably has hundreds of "clients" he needs to oversee, and it is best to call as little attention to your relative's case as possible. After a few months, when he realizes he isn't nearly as bad of a dirtbag as half of the other guys he's responsible for, he'll probably put a very low priority on his case as long as he stays employed, stays out of trouble, and shows up for all his appointments.
