Your analogy is get accurate. It's more like: commercial fisherman murders hundreds of innocent fish. Those fish usually go toward feeding whales. Why do the fishermen hate whales?

The real crime here is too many people, these cops included, use "just following orders" as justification to hand-wave away the side effects as not their problem. The intent is important here, and the headline for this article misconstrues the intent and cause of the resulting suffering. For that matter, it doesn't even go into detail about the actual suffering, just a hypothetical one.

What am I saying? This isn't even an article. Why are we treating a post on X as any source of information?
