Comparing Zombies to Criminals

From The Truth About Guns:

What is true of our interactions with Zombies is true of our interactions with criminals. The first and best defense is just to avoid them. Stay away from places where there are zombies. If you run into them, and you have time and ability, run away from them.

If you are forced into an interaction and a criminal has the drop on you, give them what they want, and do it quickly. Don’t try to reason with a criminal. ...Zombies and some sociopathic criminals just want to kill you, in which case you better be ready to resist.

If it comes to armed resistance, be prepared to act with sudden, unexpected and extreme violence and to continue until the threat is neturalized. The violence required must do bodily harm to the extent that the attacker either runs away, or is unable to act against you, giving you time to escape (note: actual Zombies will not run away, and must be destroyed).

Effectively dealing with the zombie hordes will by necessity be nasty, messy business. The unfortunate truth is that same messiness can be a real unstated dark side of self defense with a firearm. One must come to terms with the reality of that violence, especially when all options are removed by the criminal other than a choice between violent resistance or violent victimization.

Zombies are metaphors. It is more comfortable to think about gunning down mindless, brain-eating, undead monsters than a hungry, violent mob or a gang of psychopaths.
