I was recently involved in a fight where a person had a knife, and a bat. I was hit with the bat and then grabbed. I punched the person two or three times and ended the fight. before I was hit, the batter swung at my 55 year old father who was holding my minor child. The swing was a miss, but I am unsure what exactly happened after that. the police said that the person had an injury that was caused by being hit with something but I do not recall hitting them with anything. When the police arrived the weapon used on me was gone, and there were other people standing around. they never looked for the knife either. I was summoned to court for aggravated assault and so was the other person.what grounds do I stand on if any? I was origionally called there to help my child by the mothers boyfrien
