Everyone here agrees with you about the source of the problem being Muslim. The disagreement is how to ID them at the airport. And ID any paid, tricked or sympathetic person who may white, female, old, young, or non-Muslim without a record, and who STILL harbor weapons and/or explosives.
Because al Qaeda and other violent Muslims are always probing for ways for defeat security. Sending in the non-obvious is one of their later adaptations.
One FReeper on one of these threads said that, as part of profiling, Israelis interview everyone. Personally, I’d rather spend a minute going through a scanner, perfect or not.
The only problem with your scenario is that so far only actual Muzzies have planned or executed terrorist acts. And with Arabic Muz names. So far no blonds with names like Trent Hoffstratter from Iowa, or nuns, or little children, or grampas and grandmas on their way to spend Christmas with family, etc have attempted or succeeded at performing terrorist acts.
Only actual Muzzies with Muz names have.
