While Brother Breaux was going to an extreme with his view, he was correct in not relying on guns for protection. The Brother in the video was just waving a gun. He didn't have the conviction to use it. That would be the most dangerous to himself or his family. When a person has a gun, s/he has to be prepared to use it without hesitation. No JW would would have such preparation. They would hurt themselves or others or have it stolen or taken away.
Using a gun for self defense and then killing someone is not blood guilty, there is an affirmative defense for that.
Wisdom can find ways to protection without a gun. Macgyver didn't use guns, because brains are better.
