General Rules of Security & Preparedness
Weapons are the second line of defense. Outfit your home to prevent someone from gaining entry: purchase perimeter alarms, inside alarm systems, security cameras, floodlights, and secure locks. Make your house a bad home to target. Dogs or trained attack dogs are ideal.
If you may be directly affected by violence, board up your windows and barricade your doors. Eliminate entry points. If it is an all-out armageddon type situation, board up with a 4 x 8 board using 3″ screws and whatever means necessary to minimize entry points.
Ideally, having firearms and being thoroughly trained is the optimal situation. But since not everyone can get firearms for one reason or another, you should consider other weapons.
Distance is Our Freind
Think “distance” when considering your optimal choice of weapons. The last thing you would want to battle with when you have a home intruder is a knife or weapon that brings you close to your intruder. Since many home intruders are trained in knife defense, they can quickly disarm you and turn the weapon against you. A knife is not a suitable home defense weapon. Watch some videos on what a home intruder trained in knife tactics could do if they disarm you and turn the weapon against you. You will not want a knife near a home intruder.
Distance: Rule #1 keep your distance by choosing a home defense weapon that keeps the most distance between you and the intruder. Pick something that can be used across a long distance — like a taser, OC spray or bean bag gun.
