Is a head lock lethal

Answer

A head lock can be potentially highly lethal if one individual holding another individual in a head lock suddenly and unexpectedly turns into the head lock. That is, if the head lock is maintained by the right arm, a turn of the body to the right is turning into the head lock, or vice versa for a head lock maintained with the left arm, and it would likely break the neck and kill the opponent. This maneuver does not always result in a broken neck or death if not done just right, and it is not recommended that anyone try to kill an opponent. By law a defender should always use only enough force to temporarily incapacitate an aggressor and flee, unless it was absolutely and provably necessary to use lethal force. If you cannot prove beyond a reasonable doubt that you had to use lethal force you could be charged and tried for at least involuntary manslaughter and given a stiff prison sentence depending on the state one lives in and the circumstances of the killing. And you will carry a felony for the rest of your life.
