This is an excellent video. It is an excerpt of the Cato Institute video Massad Ayoob speaking about "stand your ground". To get the full explanation, watch the long (16 minute) version.

The full Cato video is 70 minutes and linked to on another post but I found the 16 minutes in this excerpt to be the most valuable.
