Check out this excerpt from "The Castle Doctrine" and find out more about the new breed of gun laws stoking the firestorm of protest surrounding the fatal shooting of an unarmed teenager named Trayvon Martin in Florida last month. When we aired our investigation in January 2009, it was the first in-depth look at the controversial legal trend sweeping the country. In this excerpt, you'll hear from Marion Hammer, the legendary gun-rights crusader and former NRA president who pioneered the first castle doctrine law in Florida and Jeannie Suk, the Harvard Law School professor who says these laws mark a radical reversal of self-defense concepts that date back to English common law. Dan Rather Reports airs Tuesdays at 8pm ET on HDNet.
