"We're all potential victims."—Peter Christ, retired police officer

Sometimes ten seconds is all the warning you get.

Sometimes you don't get a warning before all hell breaks loose.

Imagine it, if you will: It's the middle of the night. Your neighborhood is in darkness. Your household is asleep. Suddenly, you're awakened by a loud noise.

Barely ten seconds later, someone or an army of someones has crashed through your front door.

The intruders are in your home.

Your heart begins racing. Your stomach is tied in knots. The adrenaline is pumping through you.

You're not just afraid. You're terrified.

Desperate to protect yourself and your loved ones from whatever threat has invaded your home, you scramble to lay hold of something—anything—that you might use in self-defense. It might be a flashlight, a baseball bat, or that licensed and registered gun you thought you'd never need.

You brace for the confrontation.

Shadowy figures appear at the doorway, screaming orders, threatening violence, launching flash bang grenades.

Chaos reigns.
