Until I actually read the polcice report it is difficult to give you a detailed opinion as to mitigating circumstances as to the assualt and battery charge that you have facing you. However, self defense could be a viable defense for you. The victim's inability to recall events due to being intoxicated is another defense.Given the situation you are facing, it is suggested that you consult with a criminal defense attorney to assist you in trying to resolve the matter that you have written about. Possibly the court could place you on court probation if you qualify and if successful in the probation, the charge could be dismissed against you. A lesser charge could be "criminal recklessness".
