The twelfth episode discussed the advantages of the rifle (in particular, carbine) for home defense. One reason mentioned was the prevalence of body armor and even spare cartridges carried on the body. It was emphasized that the weapon is a self-defense tool ("It's a tool; it's a hammer.") and must be chosen carefully. I was surprised by the emphasis on positions/stances and the body weight distributuion in the stance (60% forward in one case)--again, so similar to the martial arts as I think of them. As usual, the importance of worrying about penetration of the ammunition--say, if you're in an apartment complex--was mentioned. Another segment discussed lights and lasers sights. Massad Ayoob talked about the need for weapon options where firearms are forbidden. He told a story about Rex Applegate using a cane to defeat two assailants late in his life, then demonstrated some cane techniques.
