My 43 year old brother lives with my parents. He is an alcoholic and will not admit his problem. He has begun to get mean when he is drunk and drinks until he passes out many times. About 6 months ago he screamed at and cussed at my 77 year old Daddy for hours. It took my husband and 3 sons to keep him from hurting him. He tried to break the window out of the car that my Daddy was sitting in so that he could hit him. My Mother is extremely protective of him and I feel somewhat paralyzed in my ability to help them. I don't know what my rights are and I need some advice. Last week he was found passed out and he was taken to the hospital. His blood alcohol level was .43. What is the best way for me to proceed the next time he gets drunk. It happens about every 6 weeks. What can I do legally and can I keep him from them? Thank you for your help in advance.
