Black people? Criminal invaders?
When was that?
You may want to familiarize yourself with, oh, the history of the United States from Reconstruction up to the Civil Rights Act of 1964. Every black person not actually working for his old master at his old job in 1866 was considered a criminal in southern states. And even in the north, an entire structure was built to “keep them out of the neighborhood” because the presumption was that if they were in a rich neighborhood without being someone’s house servant they were “up to no good.” Hence, a “criminal invader.”
