Its easy to follow the crowd when popular opinion swings in a crazy direction. Its even easier to see the writing on the wall and be one of the first to swing back, claiming some kind of honor or bravery in doing so.
Its a win-win. Up front you don't get blasted for being racist because you don't fall in line, and on the back end you're held up as a hero when you respond to what everyone has already realized but few have adjusted to yet.
I saw the same thing at a company I worked at where they found at that Black people were getting lower performance ratings and there were people in the Diversity interest group advocating getting rid of numeric ratings so, you know, instead of knowing there was bias we would… not know? Like maybe it was a management psy-op or something but that was insane.
Why do you automatically assume this? Might be related to why people wanted to hide these numbers.
If we went with the actual recommendation (e.g., to complete the analogy sandwich, "dismantle the current institution and establish a new one with a fundamentally different structure which allows for security/investigation functions to be carried out without the baggage of the previous institution"), something might actually change for the better, and we can't have that.
