I'm pretty satisfied with saying I think we should employ whatever tactics are used by the Israelis at their airports.
How 'bout we just compare their treatment of airline passengers? After all, I'm not comparing "apples to oranges;" I'm comparing apples to apples. Not everyone who uses American airports are citizens just like not everyone who uses Israeli airports are Israeli citizens.
But, I do know their method for screening passenger is a bit less intrusive, more deliberate, and more respectful than the one we've adopted here. And, they've not experienced a case of violence on any of their airliners in decades.
All without groping Nuns, teenager, or grandmas in wheelchairs.
