Are we vetting, or simply enabling "Syrian refugees"?

The UN does the initial vetting of Syrian refugees bound for the U.S.

By so doing, the U.S. has outsourced what may be the most important part of the vetting process. 

Case can be made that the  way things are now, the process actually coaches refugees, so their answers are slick and alibis tight by the time an American screener conducts his/her first interview with a refugee candidate.
