Quite a few of the talking heads on the Left are rightly pointing out that the perpetrators of the Paris attacks were not actually Syrian refugees.
They only POSED as refugees with forged docs to make border crossings easier in order to make their attacks.
According to them, it should be OK to accept REAL Syrian refugees to the US.
(Because they'd never try to get here by using that tactic. The DHS is way too smart to fall for that!)
