When Indiana today shuns desperate refugees, it is shunning people like my family.

Yes, security is critical, but I’ve known people who have gone through the refugee vetting process, and it’s a painstaking ordeal that lasts two years or more. It’s incomparably more rigorous than other pathways to the United States.

If the Islamic State wanted to dispatch a terrorist to America, it wouldn’t ask a mole to apply for refugee status, but rather to apply for a student visa to study at, say, Indiana University. Hey, governors, are you going to keep out foreign university students?

Or the Islamic State could simply send fighters who are French or Belgian citizens (like some of those behind the Paris attacks) to the U.S. as tourists, no visa required. Governors, are you planning to ban foreign tourists, too?

Refugee vetting has an excellent record. Of 785,000 refugees admitted to the United States since 9/11, just three have been arrested for terrorism-related charges, according to the Migration Policy Institute in Washington.

If Republican governors are concerned about security risks, maybe they should vet who can buy guns. People on terrorism watch lists are legally allowed to buy guns in the United States, and more than 2,000 have done so since 2004. The National Rifle Association has opposed legislation to rectify this.

Although Donald Trump fulminates about President Obama supposedly wanting to bring in 250,000 or more Syrian refugees, that’s preposterous: Obama proposes admitting 10,000 Syrian refugees over a year. That’s tiny, just 1 percent of the number that Lebanon has accepted.
