The narrative about refugee resettlement spun by the invite-the-world crowd is that refugees pose no threat to Americans. To pick only the first link to pop up in Google, see this from VOA: “UNHCR: Refugees Pose No Threat to US National Security“. This is because they are “rigorously vetted“, “the most thoroughly vetted of all people entering our nation“.
The problem is that vetting is only as good as the information available. And we simply don’t have access to information that would successfully identify potential bad guys. In my testimony on this a while back I quoted FBI Director Comey:
ormation on someone, they’ve never crossed our radar screen, they’ve never been a ripple in the pond, there will be no record of them there and so it will be challenging.
