Would You Trust This Man To Teach Your Children Transfiguration?

For futuer reference, this is Radovan Karadzic. He's a recently captured fugitive and war criminal who was the first man ever connected to the term ethnic cleansing. He's going to be on trial for overseeing the the murder of thousands of Muslims and ethnic Croats in Sarajevo and Srebrenica in the Bosnian war of the 1990's.
Now that this is clear, can we all please stop comparing him to the Headmaster of Hogwart's School for Witchcraft and Wizardry, who, to my knowledge, never committed genocide against anyone? Thanks.
