It's not true that people just sat by and watched.

There was massive public backlash and real organized resistance, especially in the streets of Minneapolis. People literally put their lives on the line, communities banded together to help migrants who were afraid to go to work or leave their homes, and they ultimately forced the government to retreat and change tactics. And it resulted in the firing of a cabinet secretary and the border patrol commander that was the face of the whole thing. And plummeting public approval that has only declined further since

A somewhat similar campaign occurred in Hong Kong, but the resistance sadly was not able to fare as well against China tyranny
