Yeah, he probably shouldn't have called the police. Since he's dead, he won't have a chance to learn from that mistake...
First, I don't care about the semantics. You can replace "murder" with "kill" in my post and the point does not change at all. "mentally/emotionally unstable" is so broad a term it is meaningless.
Not sure what you meant by it being so broad a term that it's meaningless. So, we should never use the term "mentally/emotionally unstable" at all to describe someone? All because you personally regard it to be "meaningless"? I personally find a lot of politically correct terminologies to be meaningless, but that alone does not stop others (especially leftists) from using them.
EVERYONE is unstable sometimes.
Again this doesn't make sense. Yes it can be argued that everybody is unstable sometimes, however, when you are clearly not being unstable and you say, carry a weapon in a public, you aren't going to be shot at by the police. On the other hand, when you are clearly being unstable, and you are holding a gun, then guess what? Cops are going to find that to be a very dangerous situation. Not saying they should shoot you. Just saying that they will very likely perceive you as a threat.
Mental illness is more precise.
You don't get to dictate to me what terminology to use. I still maintain that there is a difference between being mentally unstable occasionally and straight up mental illness. It's like you said, everybody is unstable sometimes. You can be occasionally mentally unstable without having a formal diagnosis of a mental illness.
Suicidal thoughts are a mental illness,
Not necessarily. My understanding is that suicidal thoughts are not always a form of mental illness, especially if it's fleeting, or if it's due to circumstances, for example, a girl who has been gang-raped might want to kill herself, and it's not because she has a mental illness.
so it's also more accurate/useful for this discussion. But again it's just semantics and doesn't matter. If you still want to talk about "mental instability", fine. The point doesn't change.
Now, the main point is that there is NEVER a guarantee of safety when dealing with people. What matters is the probabilities.
For this discussion, lets say that the baseline threat probability is for a totally normal gun owner exercising his right to open carry while walking down a street. The threat to public safety is not 0. That totally normal gun owner could suddenly decide to start shooting into a crowd, and no one would be able to stop him before people died. Society has deemed that threat probability to be acceptably small. Which means police are NOT going to shoot the open-carrying gun owner within 11 seconds of seeing him.
Now, compare that baseline probability to this incident. In order for this shooting to be justified, there must be factors which make the threat probability significantly greater than the above baseline. The factors in this incident that might be relevant are:
1. Sitting in his own home. I consider that LESS of a threat than walking down a public street.
2. Suicidal. Increased threat to himself, but not to the public.
I don't disagree with you that it's a matter of probabilities. However, that should be left to the police officer to decide. Maybe they genuinely perceived the man to be a threat, for whatever reason, then they should have the final authority to decide whether to shoot. Can they make mistakes, which they will have to answer to, in a court of law? Yes. But the principle still stands. Cops decide whether the probability of someone being a threat is high enough to warrant shooting.
And about being suicidal only being a threat to the person, it's not always the case. There are also people who want to "take other people out with them" when they are feeling suicidal. I am not saying this is what happened in this case. Just saying that you are wrong when you say suicidal means only threat to self.
