Thanks for posting the link to Innocents Betrayed. The video presents critical information that doesn't get talked about very often even in gun circles.
I like this video, although, it is graphic enough to where I wonder if it truly useful in converting people who are neutral or anti-2A. Once people have thought about and they are leaning toward the 2A, then show them Innocents Betrayed to cement in their minds that gun ownership is critical to preserving the US Constitution. Show Innocents Betrayed to a friend who has never really thought about gun ownership at all and you may give them nightmares instead. I don't know, and I making sense to you?
Here are four videos that I like to use in educating those who are neutral or anti-2A. They are better in my mind for educating the general masses. I post them here in case the OP or anyone viewing this thread hasn't seen them yet.
The last link is the first part of a two hour documentary on the origins of the 2nd Amendment here in the United States. I would recommend it alongside Innocents Betrayed to anyone who really wants to round out their study of the 2nd Amendment. I don't mean to detract from the OP's video but wanted to post these in case he or anyone else hadn't seen them.
