Shouldn't it be illegal in the US to fly a foreign country's flag on American soil? Isn't that what an invading army would do, take down the American flag and fly their own?
By the way, for those who say these Mexicans should go home, what for? As soon as they go home, Tyson and the other poultry, beef and pork corporations will bring them right back, by the bus loads. And the US government allows this.
