As for the excuse of "security," this is one of the least security-minded administrations we have had. When hundreds of illegal immigrants from terrorist-sponsoring countries were captured crossing the border from Mexico-- and then released on their own recognizance within the United States, that tells you all you need to know about this administration's concern for security.
When captured terrorists who are not covered by either the Geneva Convention or the Constitution of the United States are nevertheless put on trial in American civilian courts by the Obama Justice Department, that too tells you all you need to know about how concerned they are about national security.
The rules of criminal justice in American courts were not designed for trying terrorists. For one thing, revealing the evidence against them can reveal how our intelligence services got wind of them in the first place, and thereby endanger the lives of people who helped us nab them.
Not a lot of people in other countries, or perhaps even in this country, are going to help us stop terrorists if their role is revealed and their families are exposed to revenge by the terrorists' bloodthirsty comrades.
What do the Israeli airport security people do that American airport security do not do? They profile. They question some individuals for more than half an hour, open up all their luggage and spread the contents on the counter-- and they let others go through with scarcely a word. And it works.
Meanwhile, this administration is so hung up on political correctness that they have turned "profiling" into a bugaboo. They would rather have electronic scanners look under the clothes of nuns than to detain a Jihadist imam for some questioning.
Will America be undermined from within by an administration obsessed with political correctness and intoxicated with the adolescent thrill of exercising its new-found powers? Stay tuned.
