If I were to help another from my company by writing a statement for a VA claim, one where I would be admitting to giving him a very hard blow to the head during a barracks boxing match, that led to him vomiting shortly after, that might be causing him problems even today; is there any trouble legal or civil I could be in from having possibly caused him brain injury? Would I face any repercussion all these years later? This was in 2003 during pre-deployment training. We were all just blowing off steam, put on a pair of novelty HULK gloves and had a boxing match with all out buddies cheering us on. Well, I was very strong and a steroid abuser at the time. I knocked him out, and when he came to a few second later he started vomiting. I found out recently that he hasn't been doing well at all these years later. He has all the symptoms of a guy who suffered a serious concussion that was never diagnose. It was only about a month after the event happened that has was becoming incompetent with tasks that had been easier for him in the past, he was removed from the jobs he was doing and put on more menial tasks, never got promoted again before his discharge. Everyone thought he was basically stupid and had simply slipped through Basic and made it to a point where his incompetence was finally exposed. I'm now questioning that, or if it was that boxing match with me that essentially altered his life. He has struggled with his civilian life as well. He's in a bad way these days, and I am gutted that he's in such rough shape. The boxing match was caught on tape as well. I want to write a statement that he could use to receive VA compensation if he ends up being diagnosed with a traumatic brain injury - one which I suggested he seek. I realize it's selfish of me to be concerned for myself at all in this, but I have a wife and 3 kids. Is there any trouble I could be in for the damage caused by our boxing all these years later? Legal? Civil?
