What gets me about that one isn't even the idea of any potential appropriation. It's how amazingly tacky and clueless and in poor taste it is to use a tragic event as fictional entertainment while it's still going on (or within hours of days of its happening) and while CNN/the BBC/etc. are still reporting on it. Hint: if the authorities are still updating the body count, it's Too Soon to write about something.

I probably ought to use a stronger word that "tacky," but "tacky" is the first condemnation that jumps to mind.
