Wait, I don't want the bother of bringing a lawsuit. Can I just take the money now? If the alleged thief is innocent, they can sue me for the money to be returned. Also, I didn't just take the cash out of his pocket, I also took his car, as I suspect he used it to drive to my house to commit the crime.
