America is not England. It is a red herring that the NRA nuts use to scare gun owners with. Anytime REASONABLE gun regulation such as instant background checks or closing the "gun show loophole" is proposed, they tout it as the "slippery slope". They are nut jobs as much as the advocates of total gun bans are. Self defense is a legitimate reason for bearing arms and almost every state has written into their state constitutions laws protecting citizens from prosecution when using lethal force.
This case in England would also be problematic here in America based upon excessive force laws. In no state are you allowed to kill an intruder simply because they are in the home or to protect property. You better damn well be able to prove that your life was in danger or you are going to jail. A big problem with most gun owners in this country is that they are totally ignorant of the laws pertaining to the use of deadly force. Plenty of Americans are also serving long prison sentences for killing an intruder but could not prove that their life was in danger. Too many people with a CCW think its a license to kill any criminal and their possession of a gun is actually a major liability. Protecting your property is not a justification of the use of deadly force in the eyes of the American courts either.
I've never read of an instance where someone was charged for killing someone who broke into their home. Hell, even when I was living in Chicago and guns were ILLEGAL there were multiple cases where people illegally owning guns shot intruders and weren't charged. Now quick run to google and prove me wrong! I think you're full of shit here and this is your opinion, not fact.
Dead men tell no tales, if someone breaks into your house you shoot them dead. If it's 3am and I hear someone in my house I'm certainly not going to call out to them and ask them if they plan on doing me or mine any harm, or are they simply here to steal all of my shit. That's fucking ridiculous bro... It's well within your right to kill someone in your home if they are there unwelcomed, especially if you are in your bedroom with no means of egress. There is no time to see what there intention is. If you don't agree with this you're a damn fool. Think about it. You have a couple of kids who are in a room down the hall and you hear people walking around. I'm going to acknowledge my prescence after my shotgun is pointed at there chest with one in the pipe. If there reaction is ANYTHING except for not moving a muscle they're getting blown away. I'd also be willing to bet everything I'm not having any charges pressed against me either. Guns are not evil.
