I have been charged with a class 4 felony for aggravated assault in Illinois for telling a police officer to get his flash light out of my f...ing face before I kill him. He was questioning me at the time about a verbal argument that had taken place in my neighborhood. I had been drinking and acted like a fool. There was no physical contact between me and the officer. I acted terribly and I'm embarrassed and ashamed. I have no prior criminal record. How likely is it that I will get jail time for this first time felony?
