It’s cute that some of you guys are using the “BuT MUh RIghTZ” argument. It’s like you’re not paying attention.
Yes, you have the God-given right to preserve your life; but do you feel confident enough the court will agree you needed to shoot someone and are you willing to risk jail time and possibly bankruptcy?
Maybe the person making that decision just simply doesn't give a f*** anymore and I can't really say that I blame them... given that clown world is pretty much intolerable at this point.
Also it's a mindset thing if the person with the gun thinks that the other guy has a reasonable chance of killing them or turning them into a jibbering vegetable then shooting them would clearly be the least evil of all the choices because if you are dead or rubberlipping it, idea of appearing in court is going to be pretty much moot. If you're dead or disabled theres not going to be a shred of life left to live.
There's also cases where you can clearly be legally in the wrong but tactically or morally correct 150%. People that know this innately would even tell you as they're sitting behind bars that they would f***ing do it all over again in a heartbeat if they were forced into that position.
What is legal and what is RIGHT are two different things.
