What media bias?? The cases where the officers kill unarmed people are far too many , there is no bias in the numbers.
It is absolutely the officers' fault that he is not taking into account the age of the suspect. Exactly because he may not act 'rationally' he should give him much clearer instructions . And how can you say it is a more dangerous situation? It's a 13 old boy, not a high speed operator that can turn aim and shoot before the cop could blink. He shot because he knew he would get away with it, and he probably will.
As yourself and other astute posters noted - of course the media will focus on when things go wrong - far moreso today with available cameras, which is a good thing for transparency, obviously. But, if you polled people around the world right now about officer-related shootings of black Americans, you'd probably find that they overwhelmingly believe that we're at a peak number, and it's getting so much worse, and it's the major societal issue so and so forth.
But what if that's not true? Shouldn't we use actual stats and trends to dictate policy? Should policy be determined by public sentiment - itself simply a function of the media?
Again, I don't see how the officer is supposed to assume that a scared, 13-year old armed child is going to act rationally. It's obviously a horrible situation and we should never have gotten here.
But the fact that every poorly trained police officer in America HAS to be armed because every potential confrontee could be is the reason there are so many mistakes. And that's a policy no one seems to want to deal with, because it's much easier to talk about bias or how awful police are.
