"Then Noise Man calls the police and presses charges against Sword Man for breaking and entering and for threatening him with a weapon! So the victim of the break-in is guilty of disturbing his neighbour (and of plain old smut-mindedness), and the victim of the noise disturbance is guilty of reacting to it by trying to stop a crime! "

So inconsiderate wanker who cannot be bothered to not annoy his neighbour - thru playing stuff too loud - wins out over caring neighbour who is trying to do the socially demanded thing.

No wonder people just put their fingers in their ears and ignore calls for help!
