I see two women and one child in this picture. The majority are men who could very well do harm to Americans. But, we also know from the Paris attack that one of the eight terrorists was a woman.
Are we supposed to believe that all 20,000 refugees, that are coming to the U.S. under Obama's directive, will be properly vetted? Think about that. Are we to assume that Bashar al-Assad has provided us with birth records and arrest records for all these people? I don't think so. What are we going to do? Have them check a box indicating that they aren't a terrorist.
Don't forget. This is the same Obama Administration whose FBI interviewed the Boston Marathon bombers and Fort Hood shooter and didn't see them as threats.
