A tipster tells us that Mark Bulliet, an editor at NYC's throwaway free morning paper Metro, has been fired. The reason: Bulliet was the editor who oversaw Metro's embarrassing front-page story last Thursday about a girl who was supposedly attacked by four black girls because she was wearing a t-shirt reading "OBAMA IS MY SLAVE." As we told you last week, that story's only source was the crappy designer who had sold the t-shirt, and it's likely the whole thing was a tasteless, racist publicity stunt that Metro fell for. A source tells us that Bulliet had an intern do the story despite its incredibly poor sourcing. We've emailed Metro for a response. If you know more about the fallout, email us. [Previously]
