The Brits Are a Strange People
The odd thing is that right now I am connected to an unsecured router (my own as it happens). I have on more than one occasion used OPB (other people's broadband) in a pinch, and frankly don't care a wit if someone uses mine in a pinch as well.
The odd thing about the story is that it does not say what the owner of the broadband connection had to say on the matter.
