First of all, this isn't Star Trek, machines and collectives don't tell us how to think. Fleeing our homes, hiding under furniture in the face of criminals invading our home? Nope.
One unarmed burglar? Pretty even odds, right? Nope. Meth, extacy, K2, and combinations of that stuff make a man who looks human on the outside, and acts like something from World War Z.
I mean lights and verbal challenge are still needed to sort out the "oops wrong house" college drunk, or the friend of your kid who brought in the first armload of dirty laundry. Weapons, multiple perps and rushing you at a dead run have to be dealt with. Lately the flavor of home invasion appears to be a team of four, five or six, smashing their way into a house, occupied or not. Daylight or not.
This is a specific instance in my mind, for the argument for the double stack magazine pistol, or the AR15 for home defense.
Nobody wants to shoot anybody, but I will not be an idle witness to any one of my family, or person welcome in my home, be harmed or killed by a criminal smashing his or her way in. It's the way I was raised, the way I have trained and acted my entire life.
Of course if it comes to that, there will be aftermath. That will be dealt with when people I love are safe.
