Solution= make everyone with an Arabic or Muslim name go through a GE Ion Track.
Why even bother with detection if we could organize premature detonations instead? Say, EMP "pingers" could fry electronics and drive a spike - and detonate - a bomb with electrical detonator. For shock-sensitive materials like acetone peroxide a serious ultrasonic field could do the same.
Subject each passenger & bag to a quick slight shock. If they blow up, they're the bad guys.
"Rapid security scanning"??? Sheesh! It takes more than 12 seconds to unlace my boots.
Just let the crowd muddle through, one at a time on their way to take their shoes off...
On right side, a "strict" aisle: here, boarders pass through multiple x-rays, MRI, barking dogs, lecherous old men wearing latex gloves, and lastly members of the NYFD in wife-beaters, holding heavy lead pipes...
On left side, an express aisle: 15-foot long, wall-to-wall, 3-inch deep depression in floor. Thousands of copies of the Koran fill this shallow walkway depression.
Same thing for customs, court-houses, and welfare offices. And DMV. And Wal-Mart
Budget negligible, no unreliable technology, immediately implementable, elevates "seperation of church and state" to unheard-of levels...
X-rays - pfffttt!
Why not use current tech like:
Solid state junction Fast Neutron SPECTROMETERS
Glow discharge optical emission spectroscopy (GD-OES)
X-ray fluorescence spectrometry (XRF)
Neutron Scanners
Gamma ray scanners
Tomographic Gamma ray backscatter
and more.
These *will* fog your film tho.......
RAE Systems in San Jose, CA.
They manufacture numerous radionuclide detectors. Something I think the government should be spending more time researching and aquiring.
