It's not a Kobiyashi Maru, my friend, and you don't need a full tank of gas.
You may not need a full tank of gas, but this is exactly the Kobiyashi Maru.
For those not nerdy enough, the Kobiyashi Maru is a fictional test given to officers during training on the television show Star Trek. It's supposed to be a fighting scenario where the leader has to decide between two terrible choices; send a single crewman to his death or let the whole ship go down. The "no win" scenario.
Some people misinterpret the concept of a "no win" scenario to say that it isn't realistic because you can win. Not only can you win, but you should be working as hard as you can to win. That's the only acceptable outcome of a self-defense situation.
The thing is, every time someone has to fight, it's a no win for all involved. Many will disagree with me, but all self-defense fights are a no win. Why? Because the best you can hope for in the outcome is to get back to your regular life.
In most self-defense situations where a gun is involved, there are legal issues that must be dealt with. That will cost you time and money. Result - your life is changed, not for the better.
Then there's the emotional repercussions. Only a psychopath is not affected by causing the death of another person. It will affect everyone to different degrees, but it will affect you. A lot of people say on the internet, "I'll kill that MF and dance a jig while doing it." Yeah, that's not how reality works. Result - your life it changed, not for the better.
There are many different ways to live through the scenario in the OP. All of them involve life changing actions. In this situation, the best you can hope for is to get out without killing anyone, but you'll probably need a new car. The worst would be you have to shoot your way out, take a few people down and then see yourself on the news and youtube doing it. The liberal media and public will paint you not as a victim saving their life, but rather as a terrorist killing innocent protestors.
Yes, this is a no win scenario. If you're not prepared to deal with the backlash, why are you carrying a gun?
