Well maybe it ought to be.
Once you make the decision to be armed, any encounter you find yourself in now has the potential to be LETHAL. Once you make the decision to be armed, any encounter you find yourself in has the potential to send you to PRISON for the rest of your life instead of just a few hours or a day in county lockup for a simple fistfight. You have raised the stakes exponentially by choosing to be armed with a lethal weapon, so your legal and moral responsibilities got raised also.
Any encounter I have can turn LETHAL whether I'm armed or not, dude. Any fistfight you get into can send you to prison. The stakes aren't raised one iota, unless you draw that weapon when you shouldn't.
Yes it does.
If you kill someone with that piece of steel and claim it was in self defense, you have a legal obligation to show that you were an UNWILLING PARTICIPANT in the encounter. Its not about being a "pantywaist", or a wimp, or whether or not one has gonads. Its about whether or not you want to spend the rest of your life in prison. When I carry a gun, I DO take it seriously.
There's no requirement to be an unwilling participant. If I'm very deliberately chasing someone down to arrest them, I can still shoot the bubblegum out of them if, when I get to them, they use lethal force to resist my lawful citizen's arrest, for instance. Furthermore, if I'm in the middle of a fair fistfight with somebody, and THEY pull a lethal weapon and come at me with it, I have every right to pull my pistol and drop 'em like an 80lb bag of concrete. I'll probably be charged with something, but not unlawful homicide.
All the answers are in your copy of the Oregon Criminal Code, gentlemen. None of this is magic, or mystery, or unknowable. I don't repeat BS I heard from my CCW instructor- everything I preach is straight out of the ORS.
