That is how tax collector agents and family farm "inspectors" should have to look like. "When the people fear the government there is tyranny. When the government fears the people there is liberty."
What this picture tells me is the left wing backing up their system of virtues and values with force, while the other wing (or wings) do not defend them self, even when they clearly have the moral standing to do so. Not only do these agents have to worry about individuals taking action against them if identified, but rest assured many of them are very much targets to administrations opposing ICE in the future.
While I do advocate for privacy in private life, I certainly am against it for public official as what they are doing is claimed to be at the request or demand of the people they claim to serve. Which one of their "servants" asked them to put on a mask?
