i was talking to a judge on the special court for sierra leone which is the court that tried charles taylor for his crimes and has tried other human rights crimes and is one of these new international criminal courts that have sprung up in the past decade or so. he asked what i was researching, and i said, well, i'm looking at courts in the 19th century. and be he said, well, of course you know about the slave trade tribunal which sat in sierra leone. and i said, no, i've never heard of that, you know? and i study this. and he knew about it because of the special court for sierra leone sat in freetown which was where one of these courts sat. and be it was part of the local lore that this court had been there and had heard these cases. and it was sort of local common knowledge but not something that people were aware of elsewhere. and i discovered that the british were excellent record keepers, and so the complete archives of the courts are in the british archives in london. and so it was pretty easy the reconstruct from the archives what the courts had done. >> host: and from that spark cam
