Quite simply I'd hammer him/them within an inch of their life/lives...then feed them to the pigs. Pigs eat everything..flesh, bones the lot and don't leave much of a trace if any at all..if they're hungry.
Any leftovers would get tossed into a pit full of caustic soda and left to dissolve.
I'm easy about the law of the land if some junky/thief scumbag mothaf*cka comes creeping into my home at night....especially if I've my 8yr old daughter staying....like any father I'd die to protect her...and I mean that literally.
I'm pretty sure if I went too far then I'd be able to cover my tracks quite well...or at least that's the chance I'd be prepared to take.
Any wishy washy liberals thinking that's too brutal.....then the newspapers are full of stories where intruders are met by soft minded people only for the soft minded to be on the receiving end of the brutality...many usually end up dead....and the intruders get idiotic 10 year sentences or less.
