Gender profiling no longer viable

According to recent reports, militants allied with al Qaida have trained women with a Western appearance as suicide bombers.

The women, who may have a "non Arab" appearance and be travelling on Western passports, have been prepared for their missions by the Yemeni group responsible for the operation to blow up an airliner over the United States on Christmas Day.

At this point, I have to wonder if a goal of militants is to provoke the West into instituting regular body cavity searches at airports.

Racial profiling of terrorists now futile

The recent attempted in-flight bomb attack by a Nigerian national means that racial profiling of terrorists based on previous cases cannot merely be restricted to Arab Muslims, but also African Muslims. At this rate, it's only a matter of time before Asian and Caucasian militants are employed to get past airport screening. Back in September, Pakistan reported encountering a village of white expat German radical Muslims near the Afghan border.

Update: In 2007, two members of a bomb plot in Germany were white German nationals who had converted to Islam. Combined with the potential from Indonesian Islamic militants, no race can be ruled out as a potential threat.

Countering the body cavity bomb

It turns out that recently a suicide bomber attacked a Saudi prince by hiding the bomb in an undignified body cavity. One potential technological countermeasure that could be adapted to airport security requirements: ultrasound scans to search for detonators.
