I've heard on this forum where gun owners have multiple guns stashed in different places around their home, this would also seem to highlight that as a bad tactic.
You've managed to confuse me. The woman had a spare gun that probably saved her from being murdered , after a violent assault, to eliminate her as a witness---especially if she recognized any of her attackers. How does the video "highlight" the spare gun as a bad practice? It appears to do just the opposite.
I have a spare gun on my person when carrying in public, and an appropriate number in my home at strategic places so I'm not cut off from a weapon no matter where entry is made.
Of course, ol' retired guys like me are often accused of being paranoid. Personally, I think it's just because I know I'm not invincible like I was in my whippersnapper days.
