My question involves criminal law for the state of: Tennessee
I am 16 years old and I was recently assaulted by my 19 year old brother. The altercation ended with him being arrested, however he was released the next morning. I would like to know: what legal protection I am afforded from him, what actions can be taken against him, and to what extent he can be punished according to Tennessee law.
The incident happened while I was at my mother's house. I'm not sure how it became so violent so suddenly (I believe he may have been under the influence of drugs). I was in the kitchen when he came in the house and went straight to my mother's room. I heard him yell a lot and break some stuff. He then came out of the room and as he was exiting the house proceeded to break everything in his way (i.e., a dishwasher, a shelf, and multiple paintings and decorations). I followed my mother and step-father outside of the house after him, as I was baffled and had no idea what was going on. When I got outside I heard him threaten my mother with physical harm and destruction of her property (burn the house down). Hearing this, I spoke up, to which he attacked me. We fought for a while, with my step dad trying to break us up at first then when my brother attacked my step dad they began to fight as well. At one point my brother picked up a two by four and came at me with it, luckily I managed to dodge the worst of it. After the police came and took my information, I was taken to the ER where I received a CT scan and an X-ray. I received no serious injuries, just a lot of facial bruises as well as scrapes (which cause me to limp for the time being).
I would greatly appreciate it if someone could inform me of what legal protections I have and what I can do, as I currently have reason to fear for my physical well-being, the physical well-being of both my mother and step-father, and the possibility of coming home to a house in ruins.
