Reply #10: That's good if you're in a Hollywood movie

But realistically, can you get your wife and kids awake, alert, and positioned in your safe room in under 15 seconds? Because if there is a single weak point in that fortress such as windows (Unless you've barred them all which leads to a whole slew of other problems) it will take a determined invader no longer than that to be inside (Being already awake, alert, and ready to handle resistance).

By all means, harden your exterior, but forget the "Safe Room," it's nearly worthless. Better to invest the money in qualified close combat training. Books on the subject are useless, and no substitute.
