Doctors and medical professionals screw up and kill about 125k Americans per year. Police kill about 1k people per year and of those, maybe 50 are questionable. 5-10 get prosecuted for bad shoots. So, more people (51 avg.) get killed by lightning than die in bad shootings by police.
People are having an emotional reaction to this because an innocent, upstanding good citizen with a bright future who was minding her own business in he own home was killed by a police officer responding to a call for service. This is not supposed to happen and it freaks people out. It freaks them out so much that even though the former officer was about to be fired, was arrested and NO COPS ARE DEFENDING HIM OR HIS ACTIONS, people still bring up the Thin Blue LIne thing or cops are stupid, EVEN THOUGH THIS FORMER OFFICER HAS A DEGREE IN PHYSICS FROM UT according to a google search of his name. When LE officers, former and past, relate actual experience and knowledge about the justice system and how it works, they are accused of supporting this guy. Nothing could be further from the truth.
This is why we can't have nice things, and why we can't have discussions about race, politics, etc. Because feelz.
Asking someone's frame of reference is absolutely relevant. It goes to the reasonable officer standard and the reasonable person standard when applied at law. When they sue for medical malpractice, do they call in cops to testify as expert witnesses aginst the defendant? I would venture a guess that most of the cops on this board are probably certified experts in one or more areas of LE that relate to this shooting, so yes, it does matter what your experience is. You have every right to be upset about how this situation turned out; I'm pissed off. But, no, most don't have knowledge about patrol procedures and handling suspicious circumstances that are one of the most dangerous calls a cop can go on because there is so little information.
And none of this excuses the fact that this former cop went a welfare check and killed an innocent person, pretty much the exact opposite of what he was supposed to do. He's a FAILURE in every way and the world would have been better off if he had decided to teach high school physics, instead of being a cop.
I hope this post brings understanding and not conflict. I understand why people are so upset. Your anger is justified.
