Self defence?

So, looking at this story today - http://www.bbc.co.uk/news/uk-politics-13957587

I'm very much in 2 minds over this one. The current law states we can use 'reasonable' force to defend ourselves and our homes, therefore changing the law will be a move from reasonable to un-reasonable. Many people will argue that stabbing someone is reasonable, well if that's the case then it's already legal as the law states you can use 'reasonable' force. However, it appears that the courts disagree that stabbing is 'reasonable' and as they are the one's that set the interpretations of the law then they are right, therefore changing it so they are wrong is to change it so that we can use 'un-reasonable' force.

On the other hand, if some little scrote breaks into my house and threatens me or mine then I would want to use any force needed to remove them from my house and the threat, up to and including deadly force.

So I guess this one is a tricky one, personally I would say that we change the law to state that there is a difference in defending one's property and family in your own home, but that this does not extend outside the walls of our homes.

There was a case recently where a man chased an intruder down the street with a cricket bat, that's too much but using a cricket bat to get an intruder out of your house, that should be OK.
