Sunday morning in Chicago, a 23-year-old with a valid concealed carry license and Firearm Owner’s Identification card shot one of two people who approached him on foot after a fight, striking the alleged attacker in the body shortly before 10:30 a.m. The wounded man was listed in critical condition at an area hospital. Illinois law requires the FOID card to purchase a firearm and keep it at home, plus the license to carry it for self-defense.
