19 years old and is still living at home...

My son is 19 years old and is still living at home, when he does decide to come home that is,. Lately, he has been getting into scrapes with the police. Several arrests that only came to my attention when my house was visited by several police men/women where he was arrested. It is very difficult to talk to him as he will not open up. What do I do in this situation. He takes me for granted with little or no respect. He lacks motivation and has a bad attitude. Do I tell him to leave if he will not abide to house rules.
