The article does say that the whole process " takes eighteen to 24 months on average." It also says, “Of all the categories of persons entering the U.S., these refugees [Syrian] are the single most heavily screened and vetted,”

So that should give us time to let our emotional responses be tempered with more rational thought. Like many, my initial emotional response to Syrian refugees was, "Hell No!" But we should be better than that and use our 21st century brains to temper our primitive emotions.

If at the end of the day a refugee can't be effectively vetted, then I'll stick with "Hell no!"
