You may not legally open carry in Illinois based on People v. Aguilar, 2013 IL 112116 (2013).
Footnote #3 on Page 8 of People v. Aguilar states that following the decision in Moore, the General Assembly enacted the Firearm Concealed Carry Act. Aguilar does not address the Firearm Concealed Carry Act or the Amended Agg UUW Statutes.
