I don't know what laws are in the US but I have a very good grounding in what they are here. It is extremely rare in this country to have a genuine case of self defence come to court. We have had some high profile cases where people have misunderstood the evidence as well as the law and thought someone was lawfully defending themselves when they weren't. One case being when some intruders broke into a home, assaulted family members stole property then left. The family members freed themselves then armed with iron poles went around the street looking for the intruders, they found one and beat him unto a pulp, he didn't die but suffered extreme brain damage. They claimed self defence but they were charged and convicted. Another was the case of Tony martin who shot and killed an intruder in his house, only it wasn't quite what it seemed. He had tricked some lads into thinking he had money lying around the house and he would be away, when they broke it he disturbed them and as they ran away down the garden path he shot one of them in the back and killed him. His weapons were illegal as he'd lost his shotgun licence after threatening several times to kill people one of whom was his own brother. He was a very disturbed person, which is why he was eventually have held to have committed manslaughter by reason of diminished responsibility.
The police and the Crown Prosecution Service aren't stupid and it's actually far easier than you think to tell here what is genuine self defence and what isn't. People have been charged and found guilty for defending themselves or others because they went over the bounds of reasonable force ( incidentally this is the same standard police here are held to). Was stabbing someone 30+ times in a frenzied attack reasonable force? Was kicking them in the head after you'd rendered them unconsciousness self defence?
Certain media here make a great deal of noise about what they think are self defence cases, they have political agendas to keep to but people read them, especially non Brits and think that things must be so because the newspapers say they are. Actually they aren't.
Householders and the use of force against intruders
"Anyone can use reasonable force to protect themselves or others, or to carry out an arrest or to prevent crime. You are not expected to make fine judgements over the level of force you use in the heat of the moment. So long as you only do what you honestly and instinctively believe is necessary in the heat of the moment, that would be the strongest evidence of you acting lawfully and in self-defence. This is still the case if you use something to hand as a weapon.
As a general rule, the more extreme the circumstances and the fear felt, the more force you can lawfully use in self-defence.
The force you use must always be reasonable in the circumstances as you believe them to be. Where you are defending yourself or others from intruders in your home, it might still be reasonable in the circumstances for you to use a degree of force that is subsequently considered to be disproportionate, perhaps if you are acting in extreme circumstances in the heat of the moment and don’t have a chance to think about exactly how much force would be necessary to repel the intruder: it might seem reasonable to you at the time but, with hindsight, your actions may seem disproportionate. The law will give you the benefit of the doubt in these circumstances.
This only applies if you were acting in self-defence or to protect others in your home and the force you used was disproportionate – disproportionate force to protect property is still unlawful."
