Don't they look remarkably like Mexicans and Central Americans?
That's because (due to history, the Islamic Caliphate, etc.) THEY ARE THE SAME!
Unless someone's willing to round up all the Mexicans (citizens or not) as well, it's fruitless to rely on appearances to round up the Middle-Easterners and Pakistanis.
I still think our best bet is to minimize the internment by identifying troublemakers, like Ted Kennedy, and toss them in jail ~ without whiskey either.
The same? I think not!
