It should be Mexico's responsibilty to be a police state--it's Mexico's citizens that need controlling, not America's!
The US should pressure Mexico to control their own people--possibly by restricting trade between the US and Mexico until Mexico does more to stop its people from leaving.
That way the Mexican government will look to the liberal media as the bad guys.
But I'll bet our government won't pressure Mexico to control its citizens.
I can only guess this is because somebody somewhere is making bucks from trade with Mexico, while the average American suffers from this invasion.
