You assume a “Washington based think tank” speaks for all police? How naïve are you? Probably run by a bunch of liberal former big city police chiefs and funded by Soros.
I assume that they speak for police management. I assume that police will follow orders from their bosses as they have in every totalitarian country on earth. Human nature good buddy - how naive of you to assume otherwise. To make your assumption that the rank and file won’t follow orders says human nature is different in the USA than it is in other countries. Just ain’t so.
