This is revisionist, though, isn't it? And in a way that specifically eliminates the meaning of the protests. The protests started before the officers were charged, I believe. And while it may not be reasonable to expect the arrests to happen instantly, it's also reasonable that people doubted it would happen at all.
Assuming you mean well and all, this specific wording could nevertheless be interpreted as a dog whistle. It triggers some peoples' political immune system.
Those two words seem to express what I think is a crucial falsehood, and it works for selective communication (dog whistling) if some people get cognitive dissonance for it and others don't. We have me as an example of the former and you as an example of the latter.
I'm not saying it's intentional, but it raises hackles for me.
It never occurred to me that that rayiner might have been using some kind of dog whistle in his reply to me. It would be rather out of character, and yours seems like a needlessly uncharitable interpretation of his comment.
So it is not true that everyone agreed from the beginning as it took a week to get to the point where everyone went "oh shit this is serious".
