Grab whatever is handy.
But if you have to resort to a shootout in your own home, you have already lost. The situation should never have reached that stage in the first place. Having an intruder inside your home is an utter failure of security.
Well...
duh. Having your home invaded is, by definition, invasive. But I was on the guard force when a drunk managed to get onto Fort Myer and started banging on the
Sergeant Major of the Army's door.
Now, had the SMA "already lost"? No, he was very much intact when we rolled up. If we had pulled up to see him lying in a pool of his own blood, he would have already lost.
Your definitions are way off, and dangerous, because someone might give credence to them. I, as the righteous law-abiding homeowner, haven't "lost" unless a family member of mine is injured, or I am killed. A failure isn't good, but people being people, failures happen daily.
Nothing is impenetrable in the long run. Given the right combination of time, money, skill, determination, and sometimes sheer numbers, any barrier can be eventually defeated. Winning is keeping my family safe, with the resources we need to survive intact. Even a stack of bodies in my living room isn't "losing", so long as I am in the legal right, and my family is safe.
Do you also want to call the courageous LA Koreans who protected their communities from violence and predation "losers" too, just because they had the audacity to use lethal force? You seriously need to redefine
victory, because you currently clearly don't understand it.
Yes, a bloodless victory without need of violence is much preferable, but keeping my family safe is victory, whatever means are used to effect that. Walls, fences, strategic shrubbery, lights, alarms, community watches, and even well-trained dogs can be defeated, but if you think
the mere presence of evil means you have lost, I submit that
you've already lost, right now.
I have lost when I lose consciousness and my family is hurt. You have to own a commitment to keep fighting until you cannot move. That is nothing like looking for conflict, just the knowledge of what needs doing once conflict is joined.
