I'll add, because many people are asking on Twitter, tonight's Timothy McVeigh special is two hours long, 9-11 p.m. ET. There WILL be clips on the video page and there WILL be a podcast. Exactly when all of the online video will be available is still uncertain, so if you have a choice, you're better off catching it on TV.
What follows is the entire program, sans commercials, taken from the MSNBC site.
