“James Stanley, the attorney, is trying to get unsecured bonds assigned to as many of the defendants as he can, even if this means asking Walker to assign them a higher dollar amount. Unlike secured bonds, unsecured bonds require no money up front to get out of jail, only that the defendant pay if he or she fails to appear in court. Stanley begins each request by reminding Walker that the defendant is innocent until proven guilty. In most cases, he says the defendant cannot afford the bail that has been assigned.”
