So let's talk about the part that isn't generally agreed upon…
> It is my belief that those officers did nothing wrong.
That may be your _assumption_, but going straight to "belief" is a HUGE step considering the lack of information. We don't know that the police identified themselves. We know that the police had an _entire block_ instead of an actual address. For all we know this was a random person stepping outside to see what was, to their mind, happening "across the street". We have near-zero information about how the shooting happened.
Why the strong desire to pick a side?
I'm not saying that I think you're wrong. I just think it's odd to form a strong opinion _right now_. We know so incredibly little, why bother forming and espousing an opinion at all? Why pick a side now? You don't have to be on a team. You can just… wait. It's possible to not have an opinion — at all. We can all move along with our day. Why the rush?
On ending lives.
Given that you've formed and shared an opinion despite a near-total lack of information, it seem to me that you're of the more general opinion that cops have the right to end lives with little information. At best, information that they know has a reasonable probability of being incorrect. Cops jobs center around dealing with false information.
My question given that world view: In the spectrum between "someone was shot at this address, your life is in danger while near that address" and "there are dangerous people roaming our streets, your life is in danger", where is the line? Should cops be allowed to end the life of any person who places their hands out of sight while in their presence? There are, after all, dangerous people roaming our streets.
