joining us is paul finkelman, a professor of law and public policy at the law school. thanks for being here. >> it's a delight to be with c-span. >> you're here because you're participating in a panel called new perspectives on the 19th century slave trade? >> right. >> what did you talk about in your discussion today? >> well, the panel talked about two pieces of the slave trade. one was the kidnapping of black children from mostly philadelphia, but also other places where they were free. and this is something that historians have known a lot about, but there has not been very much research. and so two of the panelists were able to discuss research that is ongoing about kidnapping gangs. this is really kind of an early version of trafficking people, because you have three people who are grabbed off the streets, thrown into ships, taken to delaware, maryland and, from there, transported further soft. >> because delaware, maryland, would have allowed the slave trade? >> well, they wouldn't. it's illegal everywhere. kidnapping free people is illegal, even in mississippi.
