As to the easiest part of this particular topic to address- are those highly trained in hand to hand combat required to register their hands as deadly weapons in the U.S.? But before we get into that, this might all have you wondering how the myth that expert fighters do have to register their hands as deadly weapons became established and so prevalent. For example, in the past, U.S. courts have found everything from knees to elbows to teeth to be deadly weapons in court cases. When Christie and his group approached and Christie yelled his question at McNeil, McNeil subsequently misinterpreted Christie and his friends with being with the other teens and punched Daniel in the face, as well as punched Daniel’s brother, Peter. You can also see from this why an expert fighter might be much more prone to getting into trouble while defending themselves.
