Self Defence and the Law

A person may use such force as is reasonable in the circumstances in the prevention of crime or in effecting or assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large.
Section 3 Criminal Law Act 1967

People keep asking me what is self-defence as seen by the law? Well here it is once and for all. The degree of force permissible in self-defence has been defined by some legal bod as being-:
Such force as is reasonable in the circumstances in the prevention of crime. Clear... No? Well read on carefully then because I won't be going through it again.

When can you defend yourself? Do you have to wait until someone is actually throwing a punch at you? Apparently not, if someone says they are going to kick your head in that is enough and if a blow is thrown, a person isn't just limited to simply warding off a blow. But before you go out beating up every gobby little teenager, there are three catches to this train of thought.

So this self defence lark is getting a little bit limiting really and this word reasonable keeps cropping up, so it may be relevant to look at this as well. There are no specific definitions or guide lines to "reasonable" it is entirely subjective. However a modicum of common sense is required when trying to work it out, people may wish to refer to this easy to use reference table of reasonable and unreasonable force.

Are You a Reasonable Person?

Someone pushes you in a pub and says that he is going to knock your head off because he does not like the look of you. He is so drunk he can hardly stand up.
Reasonable Unreasonable
Apologise for offending him and move to the other side of the bar. He is too drunk to bother with. Gouge his eyes out so that he will never be bothered by you appearance again.

Someone is running a key down the side of your car.
ReasonableUnreasonable
Shout at him to leave your car alone and if possible restrain him until the local representative of the law enforcement community arrives to take charge of the situation. Sneak up and knock him out with a brick, tie him up, get in you car, drive repeatedly over him saying You won't need the key because when I'm finished I'll slide you under the door!.

Someone comes running at you with a large kitchen knife upraised shouting threats to kill you.
ReasonableUnreasonable
Do whatever you can. Worry about reasonableness later. Very Little.

On a more serious note, if there has been an attack so that defence is reasonably necessary, it will be recognised that a person defending themselves cannot weigh to a nicety the exact measure of their defensive action. If in a moment of unexpected fear or anguish a person had only done what they honestly and instinctively thought was necessary that would be the best evidence anyone could offer that reasonable force was used.

It is my opinion that the level of force used in defence is directly related to that used in attack and would escalate in response. However at the end of the day it must be noted that everyone must be accountable for his or her own actions and as long as you can justify your actions as reasonable then you will be okay.
