That's debatable. You could do that, but alot of stuff wouldn't add up when the cops did their eventual investigation. In this case the accomplice ran away and got away and take was known.
Honestly another reason I'd have no problem killing someone who breaks in my house if god forbid that unfortunate situation ever happened to me is because I don't know what that person is capable of, who their affiliated with, and/or them potentially wanting payback later down the line. If their brazen enough to break into a persons house with malicious intent, I don't think its a stretch to say that they might eventually come looking for payback as someone who breaks into houses isn't working with a full deck.
