Duh!
The police weren't the target here, they just got in the way of a domestic issue. As such, there's very little reason for them to fear for their lives.
You really do seem to have an inability to view police-related matters objectively, and this appears to lead to a fairly large volume of contradictory posts on your part. Unlike many others, I don't assume that this is due to some inherent racism on your part (I suspect that's more a matter of selection bias in the articles and events discussed, as well as the framing of the OP).
I do, however, think that your innate response is to always assume that the cops are right, regardless of whether that assumption makes any sense, and regardless of whether that assumption leads to tacit acceptance of gross misconduct on the part of law enforcement.
Look - I've got a lot of military and police in my family. For the most part, I'm probably more accepting of an authoritarian approach than most people on TF. I have an innate respect for authority that I think is both reasonable and justified... but it has limits. And I recognize that not all authority is beneficial, and not all acting on the claim of authority do a good job of it. With authority comes responsibility, and it's our duty as citizens to be the guardians of that responsibility. When we see those in authority acting without responsibility, or in opposition to their responsibility, it is our duty to speak up. That's the price of them having authority in the first place.
And it's really, really, really hard to avoid seeing and acknowledging that there is racial bias in the system for law enforcement. It's not necessarily racism on the part of the individual officers - that's very rarely the case. But there is racial bias in how police interact with the public, and it results in highly disparate and unjust responses by those we've deemed the protectors of justice. As a citizen of the US, it is our duty and obligation to speak up against that systemic bias, to bring it to light, and in doing so preserve the appropriate authority of law enforcement.
