I have a son that will be 18 on 4/16/08, he has became totally uncontrolable. He has been caught stealing coolers of beer but the owener would not press charges. He has dropped out of school, refuses to work and will not do anything around the house but make messes and tear things up. He continually brings pot in the house. His older brother is home after getting out of a army prison and is trying to turn his life around and cannot be having this go on. Can I legally kick him out and if he wont leave have him physically removed by the police? I am in the state of Illinois.
