My friend Scott Richert is right: there is a problem. But excluding all “adherents of Islam” from the US isn’t the solution. To begin with, a real terrorist isn’t going to proclaim his (or her) adherence to Islam upon entering the US. How hard would it be to lie about it?

Secondly, what about all those Muslims already living in the US? Is Scott proposing that we deport all 2 million or so —including the Black Muslims?

Good luck with that, Scott. The only thing more unlikely is a sea-change in American foreign policy that would dry up the real sources of support for terrorism.
