NO SERIOUSLY. WHAT THE FUCK.
According to this article at the BBC site
the headstonewas taken sometime between Tuesday afternoon and Wednesday morning.
I don't think I have to remotely go into how fucking disrespectable (and for that matter deplorable) of an act this was. It doesn't make you the world's biggest Joy Division fan to have stolen this. It makes you the world's biggest asshole.
Lets hope the person will feel guilty and return it. :/
