Sorry, WHAT is a straw man argument?
There were no women or children in the house. Fact.
The man apparently opened his door without checking who was behind it - personally, I think that's odd.
And, no, I haven't said anywhere that I would not defend myself or my children against an intruder.
I have said that I would not defend my PROPERTY against an intruder if I thought that (s)he could do lasting harm to me or my family - and i don't think waving a knife around (rather than using it immediately) is a very good indicator of that. I would be especially worried that, in tackling a man with a knife, I or moy family would LOSE.
I have also said that I would not stab a man in the back; and that, however bad a criminal is as a person, there may well be other, innocent people harmed by his death.
In other words, I think that taking a human life is a very big deal. This man did it in the heat of the moment; people on this thread are implying that, heat of the moment or not, it was somehow okay because the man was a burglar. And it really isn't. It's certainly not something I would brag about. I think I'd be in bits, to be honest, just like this man probably is.
I suspect he's got even less time for that sort of old bollocks than I have as he now has a human life on his conscience.
