Not shocked exactly, because obviously I already knew slavery was (and is) a terrible thing, but I was listening to a podcast that told the story of Ellen and William Craft's escape from slavery, and with the amount of restrictions and punishments in place to make such a thing as difficult and risky as possible, it's amazing how they or anyone else ever succeeded. And then even after they got to a so-called free state, it was legal for bounty hunters to capture them and take them back. Awful.
