Ideas for History Day 2011?

I'm one of those people who're a bit... morbid. History Day 2011's theme is 'Debate and Diplomacy'. I can NOT, for the life of me, think of ANYTHING that will interest me to do for this project! The kinds of things I study are things like Jack the Ripper, Elizabeth Bathory, Bram Stoker, the 'Black Dahlia' murder, the Manson murders, Marilyn Manson, Rammstein, other more modern or not so 'debate and diplomacy'-ish. I have to have my papers done by the end of a 45-minute cl period tomorrow, and still have no idea what to do! Can anyone help me find something that I'll find interesting to study? I've been looking for nearly an hour and can't find any good topics. Thank you!
