Bud, i know exactly the fury that you feel, My best friends sister is a crack w-ore, and has robbed him and his family of everything, and she runs with a crowed of crackheads, I was once at his house and his sister and some of her crack possie came in and started to take stuff, thats when my friend and my self both drew our guns, him a 12guage, and me my glock 40cal. It was not the smartest thing that we have done, because the rage got so bad we both emptied our guns on the car they arrived in, luckily no one was killed.
I cant imagine the pain you are going through right now with your brothers ignorance, and poor descision making, but you need to put him in rehab, for his problem. Please be careful in your actions and dont do something you will regreat in the long run.
I wish you and your brother the best, and will keep you and your family in my thoughts and prayers.
