Oh, then it's not correct to claim that something in your possession that isn't stolen can't become stolen without leaving your possession.
You can easily possess an item that hasn't been stolen, but upon some eventuality, no longer belongs to you that you still possess. An expired library book, for example, or a rented car.
Perhaps you've entered into an agreement involving collateral that you've violated. An item you've maintained possession of will no longer be yours when the collateral becomes the property of the person you've entered into the agreement with.
