What Is The Difference Between An ISIS Terrorist And A Freedom Fighter: "Appropriate Vetting"

As we reported yesterday, in addition to Turkey and Saudi forming an alliance to topple Syria's despised anti-Qatar nat gas pipeline leader, Bashar Assad, the US has now begun training and arming Syrian rebels. But how will the US know it is arming Syrian rebels, aka opposition "freedom fighters" and al-Nusra or Islamic State jihadists who will promptly turn around and use the same weapons and training against the US?

The answer: "appropriate vetting." No, really.
