I agree with Deborah about the police (at least given the information we have thus far) did not act incorrectly in this situation. The sad truth is that even if someone is clearly in an irrational state (Scout was shouting "shoot me"), there are standards that police officers must follow for their own safety and the safety of others. That was seemingly followed here, as the police spent a long time trying to talk them down before being forced to act when charged with a knife. (Even then, it looks as though they waited longer to fire than is typical.) If they did not follow the guidelines and one of them or another civilian was injured, the story would in turn be questioning why they didn't follow procedure. There is no winning scenario here essentially.
What has really gotten to me however is the comments about Scout personally I've seen throughout the day while reading articles. This is the first such incident I've been conscious of since coming out to myself, and it is hard to just ignore the hatred like I used to. Even if the gender identity (or sexuality) issues are completely beside the point in this case, people still can't help but make them front and center. Not understanding non-binary identification and the accompanying "innocent" misgendering... I get it, it's can be a hard concept for most people to wrap their heads around. But so many people do it so purposefully as a means of, only somewhat metaphorically, spitting on Scout's grave it blows my mind--not to mention terrifies me. Even if this is just a vocal minority trading on internet anonymity, I don't understand how people can be so far gone they take joy in the tragic death of someone who suffered from mental health issues (not being trans of course, but supposedly Scout had a number of actual conditions).
I'm also angry with myself because while I commented in general about the topic using my name and e-mail address, when someone was talking about "one of them" (as negatively as possible), I could only bring myself to post anonymously "well, I'm "one of them" and..." in defense.
