The trial judge appoints the county Office of the Public Defender, which assigns the individual assistant public defender. Whether a person is indigent is left to the trial court's discretion based on as complete a financial picture as possible; a person need not be entirely without funds to be found indigent, and a court may not refuse appointment solely because the defendant posted bail. The Office of the State Appellate Defender handles appeals for indigent defendants. Ill. S. Ct. R. 401(a); People v. Campbell, 224 Ill. 2d 80 (2007); Burnette v.
