“How could a refugee from Iraq with ties to ISIS slip through to U.S.?”
What a stupid *** question!
News flash, Turd-world countries don’t issue birth certificates or even keep records of births and deaths. There is no way of telling if they are who they say they are.
Well, actually they do issue birth certificates, and they do keep records of births, marriages and deaths. The problem is that their record keeping is a little spotty, and many of these locations have become war zones. Any government building frequently becomes a strongpoint for the army defending a city, and draws a lot of firepower from the army trying to take the city. So frequently the buildings, and the public records they contain, are destroyed as a result of the war.
That isn't our problem. I'm sorry but our national security, and our duty to keep American civilians safe, comes first. Anyone coming into this country from a war zone, or a Muslim country where terrorists have been active, must be thoroughly vetted.
