Ruby Ridge: 20 years later

On Aug. 21, 1992, a team of U.S. marshals scouting the forest to find suitable places to ambush and arrest Randy Weaver, an Army veteran for possible ties to white supremacist and anti-government groups, came across his friend, Kevin Harris, and Weaver's 14-year-old son Samuel in the woods. A gunfight broke out. Samuel Weaver and Deputy U.S. Marshal William Degan were killed.
