I don't bash cops but I do call it like I see it. If they're fucked up I ain't going to bat for 'em, I'll call 'em out. I don't like fucked up HUMANS regardless of their job. No love for blue falcons.
That said, I've got a bit of experience with this, with what SWAT does when they're called to a house. I installed security for years and on two cases I had families not believe the system worked, that the cops wouldn't come. After I left one day, the daughters talked their mom into setting it off. They didn't wanna hear the horn so they armed it and used the DURESS code to disarm it. No alarm, silent signal sent saying they were being held hostage. It's a priority signal akin to a fire alarm --they just dispatch ready for action, they don't call, they don't wanna hear a password.
When they got there, they were waiting for 'em, so in this case, they just threw the family on the ground in the front yard at gunpoint until all was clear. It was funny, they didn't get mad but called very excited to tell me it sure as shit worked! It could have ended up worse though. They were expecting a hostage situation.
Then one time in Memphis, a similar situation happened and they ended up getting the FBI hostage rescue team, not the locals! They'd been in town and training and other stuff I guess (at one point someone stole their van full of weapons and demo, abandoned it with all the shit inside once they realized what they took). Anyway, they didn't fuck around and blew out windows and used assloads of gas grenades on that one. They promised they'd take the alarm more serious next time.
So in cases where cops fuck up or or where they're just murdering scum, that's different. Accidents are different if not negligent. And situations where they get away with the most heinous crimes simply because of a badge doesn't do them or the justice system any favors to the people. But this? Negligence lies with the one that called them. IMO, what counts as a good shot gets elevated on a tactical house clearing exercise where you're expecting resistance. Cop, soldier, if you've carried a rifle and cleared a house you know what I mean. I don't know all the details, but on the surface I'd think the cop probably did what he thought was truly right given his information.
If you consider it, both the cop who fired and the person shot were victims in this.
Still sad, and they need to make sure everyone in the gaming community gets weekly reports on this fucker so they don't forget him anytime soon.
