My question involves criminal law for the state of: Tennessee
Question at very bottom, but short story of what happen.
My wife's sister started dating this guys that basically made her cut all ties with her. So I stopped by their house. They both came to the door and me him got into basically a cussing battle. Him threatening that he wanted punch me and so on. They close the door, then she opened it back up and I was talking to her about calling her sister. Anyway I thought he was in back and he ended up sneaking up behind me. I took a full force blow to the back of the head. Which I went forward and ended up in his house. We were fighting, I was dazed from the blow to back of head and he ended up on top of me. He then picked a empty beer bottle up and said he would F me up. Then he smashed it right above bridge of my nose. Cops were called, my wife showed up and he let me up then. I left cause my son was with me and seen it all. I didn't know what would happen. But more I think about the sucker punch I think I want press charges.
My question is. How would this play out with me ending up in his house from the hit behind my back to the head. Obviously was trying knock me out from that. I only stopped by to tell the sister to call my wife cause she has been missing her.
