It has to do with perceived risk. I have a good sized fire extinguisher on the wall outside the kitchen doorway. I've never needed it and don't expect to need it today. I bought it "in case". If I could know there was going to be a fire in the kitchen on a certain day at a certain time, I would have the fire department standing by with hoses run and charged, I would have all flammable materials removed from the room, a sprinkler system in place, etc.
I think the day to day risk is fairly low, so I have a fire extinguisher, I practice good safety habits when using the stove, and I don't spend time and money on further safety measures.
We all make assessments based on what we think the likelihood of an incident. If I knew I was going to be in a gunfight, I'd stay home. If I had to go out, I would take my advice from the Marines.
• Bring a weapon. Bring a backup weapon. Bring all of your friends who have weapons. Bring their friends who have weapons.If I got up knowing I was going to face a rabid deer in a parking lot, or any other feral animal, I would make different choices about my carry weapons. My last post I asked what you would have with you on a typical day. Here's the next question. If you could have a Minority Report style warning, what would you be carrying when Zombie Bambi came charging across the asphalt?
• Anything worth shooting is worth shooting twice. Ammo is cheap. Life is expensive.
• Only hits count. Close doesn't count. The only thing worse than a miss is a slow miss.
• If your shooting stance is good, you're probably not moving fast enough, nor using cover correctly.
• Move away from your attacker. Distance is your friend. (Lateral and diagonal movement are preferred.)
• In ten years nobody will remember the details of caliber, stance, or tactics. They will only remember who lived and who didn't.
• If you are not shooting, you should be communicating, reloading, and running.
• Accuracy is relative: most combat shooting is more dependent on "pucker factor" than the inherent accuracy of the weapon.
• Use a weapon that works EVERY TIME. "All skill is in vain when an Angel pisses in the flintlock of your musket."
• There are no rules, always cheat; always win. The only unfair fight is the one you lose.
• Have a plan.
• Have a back-up plan, because the first one won't work.
• Flank your adversary when possible. Protect yours.
• Don't drop your guard.
• Decide to be aggressive ENOUGH, quickly ENOUGH.
