Where are the bodies buried?

I know it makes for sensational headlines but I am fed up with being told that we have witnessed assassinations. As far as I can see Mike Rann is still alive,  indeed so is Kevin Rudd.  As we look to the other parties, too, we can see a parade of former deposed leaders still alive and kicking.
We don't assassinate leaders in this country at all. We take leadership seriously and the competition is strong and robust. Sometimes you win and sometimes you lose, but there are no bodies buried anywhere as far as I can tell.
