At first Trump included American Muslims, saying if they left the country they could NOT reenter.
The extremists we need to find are being recruited from within. The husband & Hasan are prime examples. But they are lone wolves, nearly impossible to label prior.
We have extremists & fanatics of many stripes. They all should be weeded out in an ideal world. But that's not going to happen.
Nidal Malik Hasan (born September 8, 1970) is an American convicted of fatally shooting 13 people and injuring more than 30 others in the Fort Hood mass shooting on November 5, 2009.[3] Hasan was a United States Army psychiatrist and Medical Corps major who admitted to the shootings at his court-martial in August 2013

"It's my work," he said, "I don't ask anybody for who or what they want to do with the passports."
