Mock trial primer videos

A company called Before Class Media has a couple of videos on its website teaching basic trial skills. Go there and you'll find stuff on opening, closing, direct, and moving about the courtroom. The videos are behind a paywall, but they've posted the opening statement video (which, for a second, I thought ripped off the theme song from Shaft) on their blog, Trial Skills Live. In the blog's archive section (on the left side of the page), you can find some free articles that talk about the same sort of topics.
