honestly that article doesnt say whether the burglar was armed with any weapon and attacking someone who has a sword is very unlikely unless your completely mental.
So we have two scenarios they either lied about the burglar attacking someone with a sword or the bloke was a mental.
If the guy was a mental then is it right to execute someone just because there currently lacking sanity and are struggling to tell right from wrong and are also unlikely to obay being told to leave.
Honestly i think a sword is probably the worst weapon to have when trying to defend yourself without killing someone especially if there not skilled in using it.
So the moral of the story is if you don't want someone's death on your conscience don't go and confront a possible mental burglar with a sword or machete take a baseball bat instead.
Because in reality if the burglar has a gun and you turn up with a sword
it would end up like this

and if he didn't have a gun unless you were retarded you should be able to beat on his ass with a baseball bat without killing or maiming him.
