It's not normally dangerous, on average. That doesn't mean confronting an armed suspect in a dangerous part of town is "safe" and that there's no reason for officers to get jumpy when that person turns and appears to point a concealed gun at them.
I'm not saying I know a better solution, but punishing officers for acting in what they believed to be self-defense in a very scary life-threatening situation doesn't seem particularly helpful. If you put your employees in a situation where they feel like they have to chose between a possible trip to jail and a possible trip to the morgue, they're going to pick jail every time, assuming they're even dumb enough to put themselves in that situation by working for you in the first place.
I agree it's not the correct solution because the issue is systemic, not individual. Punishing individual officers won't affect the overlying system.
But it's important to note that officers are specifically taught to be jumpy and aggressive. That's not a natural response. The reason we see so many accidental shooting is because the training around it encourages it. Accidentally shooting a few innocent people in the pursuit of stamping out crime is a necessary evil in the eyes of American police.
Ultimately, the police only really know how to shoot, and we put them in situations they're not equipped to handle. It's not shocking, then, that people end up getting shot. They truly have no business doing wellness calls, or mental health assistance, or even routine traffic stops.
