Burglar v's self-defence

[Joanne]

So, you're in the house and burglars get in despite a sign saying 'No valuables left in here overnight', you're scared and end up clobbering one or shooting them like Tony Martin did. What is reasonable self defence? Will it lead to burglars burgling with weapons?

I did agree with Tony Martin and at the time a neighbour of mine did say, Mr Martin should have got 10 ears for not shooting both of them whic they were both 'seasoned' (if you can call it that) criminals.
What does everyone think?

Reasonable force, yes. But unfortunately Tony shot the guy in the back when he was already running away apparently. So this can't be considered reasonable force (even though the b........s shouldn't have been there anyway). I understand people's feelings on this but giving people carte blanche to murder someone purely if there are grounds to justify it makes me uncomfortable. Having said that he wasn't inside for long and with the greatest of respect to his victim's family we really didn't lose a potentially valuable member of society when he was killed.
