The current laws on property defence over here are insanely restrictive, though I'd question allowing people to use lethal force to defend anything other than themselves and their family/friends. Rather I'd support a much laxer definition of 'reasonable force' in the current legislation. (Not to mention limiting the number of situations in which trespassers can take the property owners to court.)
Isn't the standard 'proportionate force' no matter what the circumstances are?
A wise US jurist once observed (Learned Hand or Oliver Wendell Holmes, I'm not sure which) that 'The law does not demand detached reflection in the face of an upraised knife'.
From what little I've seen of UK law in action, it seems that the UK does demand 'detached reflection', and frankly that standard will see innocent people packed off to prison for defending their homes.
This is one of the premises behind the laws in most US states that give wide latitude to homeowners who use deadly force to defend their dwellings. Another premise is the 'castle doctrine'.
In any case, in most US states a much looser standard applies for the use of lethal force to defend one's home than would apply in other self-defense situations.
The prevailing US standard for self defense outside of the home is somewhat different.
Here's what my state's law is:
IC 35-41-3-2
Use of force to protect person or property
Sec. 2. (a) A person is justified in using reasonable force against another person to protect the person or a third person from what the person reasonably believes to be the imminent use of unlawful force. However, a person is justified in using deadly force only if the person reasonably believes that that force is necessary to prevent serious bodily injury to the person or a third person or the commission of a forcible felony. No person in this state shall be placed in legal jeopardy of any kind whatsoever for protecting the person or a third person by reasonable means necessary.
(b) A person is justified in using reasonable force, including deadly force, against another person if the person reasonably believes that the force is necessary to prevent or terminate the other person's unlawful entry of or attack on the person's dwelling or curtilage.
(c) With respect to property other than a dwelling or curtilage, a person is justified in using reasonable force against another person if the person reasonably believes that the force is necessary to immediately prevent or terminate the other person's trespass on or criminal interference with property lawfully in the person's possession, lawfully in possession of a member of the person's immediate family, or belonging to a person whose property the person has authority to protect. However, a person is not justified in using deadly force unless that force is justified under subsection (a).
Let's look at the legal definitions of the key words in that statute.
IC 35-41-1-4
"Bodily injury" defined
Sec. 4. "Bodily injury" means any impairment of physical condition, including physical pain.
IC 35-41-1-7
"Deadly force" defined
Sec. 7. "Deadly force" means force that creates a substantial risk of serious bodily injury.
IC 35-41-1-10
"Dwelling" defined
Sec. 10. "Dwelling" means a building, structure, or other enclosed space, permanent or temporary, movable or fixed, that is a person's home or place of lodging.
IC 35-41-1-11
"Forcible felony" defined
Sec. 11. "Forcible felony" means a felony that involves the use or threat of force against a human being, or in which there is imminent danger of bodily injury to a human being.
"Serious bodily injury" defined
Sec. 25. "Serious bodily injury" means bodily injury that creates a substantial risk of death or that causes:
(1) serious permanent disfigurement;
(2) unconsciousness;
(3) extreme pain;
(4) permanent or protracted loss or impairment of the function of a bodily member or organ; or
(5) loss of a fetus.
Now that we have the legal definitions, we can determine what level of force would be legal in a particular situation.
However, the key word that isn't defined in the law is 'reasonable'.
What this means is that would an average person
knowing the facts as you knew them at the time do what you did in the situation.
In other words, it would be reasonable for me to use deadly force to defend myself against a 16 year old coming at me with a lead pipe while threatening to crush my skull.
It would be unreasonable for me to use deadly force in that situation if the person with the pipe was an 8 year old.
Similiarly, it would be reasonable for me to draw my own (legally carried) gun and shoot someone who threatens me with a firearm, even if it later came out that the 'gun' in question was a realistic looking replica or wasn't loaded.
The facts
as I knew them at the time was that someone was threatening me with a gun. I had no way of knowing if it was unloaded, a replica, or an air rifle (which would still justify the use of deadly force, btw.).
It would be unreasonable if I shot someone who threatened me with an orange toy pistol.
Let's apply the Indiana statute on defense of dwelling to the Martin situation.
Eastern Daily Press Storyboard
Going by this storyboard, do you think it was a use of 'reasonable force' to fire a shotgun at unknown intruders in your home in the dark?
I do, and I'll guarantee you that if this had happened in Indiana 2 things would have been different.
One is that Martin wouldn't have been convicted of anything.
Two is that both burglars would probably have died because here he would have had access to much more effective loads (buckshot or slugs instead of birdshot) for his shotgun.
Colorado's statute is even less restrictive:
1) The general assembly hereby recognizes that the citizens of Colorado have a right to expect absolute safety within their own homes. (2) Notwithstanding the provisions of section 18-1-704, any occupant of a dwelling is justified in using any degree of physical force, including deadly physical force, against another person when that other person has made an unlawful entry into the dwelling, and when the occupant has a reasonable belief that such other person has committed a crime in the dwelling in addition to the uninvited entry, or is committing or intends to commit a crime against a person or property in addition to the uninvited entry, and when the occupant reasonably believes that such other person might use any physical force, no matter how slight, against any occupant. (3) Any occupant of a dwelling using physical force, including deadly physical force, in accordance with the provisions of subsection (2) of this section shall be immune from criminal prosecution for the use of such force. (4) Any occupant of a dwelling using physical force, including deadly physical force, in accordance with the provisions of subsection (2) of this section shall be immune from any civil liability for injuries or death resulting from the use of such force.
Perhaps the UK should adopt Colorado's law.
