Is violence ever a good thing? Is violence ever justified? Many people would say "no" but in this video we look at the challenging arguments that say, "yes". We look at times when violence has stopped bullies, muggers, terrorists, home invaders, and wild dogs; times when it has protected the innocent, saved lives, established peace, and protected freedom for cities, nations and continents. We consider that on many of these occasions those involved were even called "heroes". This is the argument for a just war.
