Quoted from one of the below articles:
"Authorities say no charges will be filed against an Uber driver who shot and wounded a gunman who opened fire on a crowd of people in Logan Square over the weekend.
The driver had a concealed-carry permit and acted in the defense of himself and others, Assistant State's Attorney Barry Quinn said in court Sunday."
