I imagine that all gun owners eventually play out in their mind a scenario where they have to take a life in self defense. It is unpleasant to think about, but like many problems in life, it is best considered ahead of time and not in the heat of the moment. Apart from the violence of the incident, we also need to concern ourselves with legalities. It’s important to know the law regarding self defense in your jurisdiction, and mentally rehearse your interactions with responding police.
There are a few different approaches to this. Some people expect to trust the police implicitly. Some people are comfortable going with a short prepared speech to the responding officer. Some people plan to invoke their 5th amendment rights right from the start and not talk to anyone but their lawyer. I cannot tell you which approach is best for you. I am not a lawyer and am not qualified to tell you what to do.
I can, however, tell you unequivocally that following the advice in the video below is absolutely the worst thing you can do in any jurisdiction:
Doing as this man says will PUT YOU ON DEATH ROW. I am so not kidding. This is the most irresponsible, idiotic, insanely stupid legal advice that I’ve ever seen someone give. If this person gives you advice on anything, do the opposite!
Incidentally, if this character ever does get involved in a self defense shooting, he’s probably screwed. Self fulfilling prophesy, I guess.
