Shoot illegal aliens in the legs

First of all, we were migrants when we came to America and killed the Indians. The people crossing the border are illegal aliens.

It worked for thousands of years around cities. It worked in China. It worked in Berlin during the cold war. It works around billionaires estates. It works pretty well at keeping people out. If Mexicans love Mexico so much why are they fleeing?
