Problem there is they will keep doing it again and again if theres no deterrent, I remember some old geezer got burgled multiple times by the same scum bag because they found it easy to do.
Anyone who enters your house and is up to no good, is fair game in my books and I will slaughter them.
I sort of see the point here, but insurance is for just this type of thing. Obviously I would take other measures like ensuring that my property was well secured (locks etc)
My point mainly stood for arguments sake of "don't put yourself and others at risk for the sake of a few valuables." - Insurance covers these. And they are (in most cases) replaceable.
Lives are not.
