I have an idea for a “deep check”. Are they Muslim? Then DON’T LET THEM INTO THE COUNTRY!
Too late for Minnesota - they have already built their Muslim population up with the importation in past years of the Somalian immigrants, who, oddly enough, have shown an uncommon sympathy for various forms of Islamic Jihadist radicals, some of them returning to become ISIS warriors, others drawn back to Somalia to join Al-Shabaab, an al-Qaeda offshoot.
Minnesota is in perhaps too deep for them to be revived, short of stripping citizenship from the Somali colony and transporting them all back to Africa.
Ding-ding-ding, definitely a winner.
