Look at it from a conservative perspective: The United States implemented certain policies. People responded in exactly the way would be expected from those policies. Some isn’t invading when you invited them...
Policies don't negate or invalidate laws or the Constitution regarding securing our borders and or entering this country illegally.
Again, we scattered our military all over the planet for 50 years, all while we were incrementally and systematically invaded by tens of millions of criminals, right here at home.
