What's that story got to do with gnu laws anyway? I mean how would it have panned out better if one of those people had shot the fella ringing the doorbell?

Not to mention some other guy who might be ringing the doorbell because he was a Jehovah's Witness or a postman?

All the statistics I've seen seem to indicate that the most likely person to get shot by householders with guns are other members of their family and harmless visitors.
