I presume you are not a lawyer or law student. (Neither am I.) Therefore I would start with a couple of books on the Constitution and Bill of Rights that were written for general audiences to get a feel for how they've been applied in real cases, to set a backdrop for what you want to talk about. Two recommendations: "In Our Defense - The Bill of Rights in Action", Ellen Alderman and Caroline Kennedy [yes, *that* Caroline Kennedy], Morrow, ISBN 0-688-07801-X. "May It Please The Court", Peter Irons, ed. (Book with optional cassettes). Narrated excerpts from actual audio recordings of important Supreme Court cases since 1955. I don't have the ISBN number because I've since given this to my dad. Very well done. Phil
