I'd heard that in 1672, a Dutch mob killed and ate their prime minister, Johan de Witt. He doesn't look all that tasty to me. I did some research on it (that is, I read a wikepedia article). It's a horrific story, suitable for Warhammer or Lamentations of the Flame Princess fans. It'd probably make a great short story, as well. Sad thing is, we can't really prove he was eaten. Here's what wikipedia has to say about it.
