I understand what the words nominally mean, thanks. But based on America's long, long history of de jure and de facto segregation by race, class, and income level, it's reasonable for people on the sharp end of that to not take "freedom of movement" very seriously as some sort of American core principle.

It reminds me of this classic line: “The law, in its majestic equality, forbids rich and poor alike to sleep under bridges, to beg in the streets, and to steal loaves of bread.” -- Anatole France
