This documentary is a solid and enjoyable examination of the key historical events that shaped presidential protection, an overview of the secret service's two principal duties (safeguarding both the commander-in-chief and the nation's currency), and a demonstration of some of the training and procedures involved in presidential security. The video is of pretty good quality, and as someone who is a West Wing fan, a political science nut, and a fan of educational/documentary film-making, I really felt that this doc put it all together nicely. All of the interviews, anecdotes, and various pieces of footage were both interesting and quite informative. It's good stuff.
