At the moment the government with 15% hardcore support is rounding up people on the streets en masse, violating decades of established practices, while harming industrial base that depend on work of those people. And somehow pretty much everyone peacefully goes along with it. Or get occasionally shot.
And? Minnesota is under strike right now and Arizona's AG just told its citizens that they can legally shoot ICE if they don't properly identify themselves or have a warrant or legal cause to arrest them. Still 95% of the nation is operating as normal, but that isn't possible when people are being actively bombed.
That is exactly the point. It's working because everyone is peacefully going along with it. They have the consent - or at least acquiescence - of the governed. That's why they have no issues.
It is, therefore, not remotely relevant to your post starting this whole thread off saying that the consent of the governed is irrelevant and all you need is tanks.
