Reasonable Force

Reasonable force refers to the amount of force that is necessary for a person to defend himself or his property, without going overboard. It is especially important to prove whether or not the force a person used was reasonable in order to determine his level of liability for the crime. Hence why reasonable force is also referred to as “legal force.” For instance, a father who gets into an argument with his son’s baseball coach, shoving him with his hands, has started the conflict. If the coach, in defending himself, picks up a baseball bat and slams it into the father’s head several times, it could not reasonably be considered self defense.

If a person can prove that he used reasonable force to defend himself, he may be able to avoid being prosecuted for a crime.

If a person uses more force than what would be considered necessary to protect himself from an aggressor, then this would be considered excessive or unreasonable force. Once excessive force has been proven, then the defendant’s self defense argument is considered forfeited. For instance, a defendant is justified in using force that is intended or likely to cause death or severe injury if someone violently enters his home, and he believes such force is necessary to prevent harm from coming to himself, or to another person in the home.
