A SENSIBLE ALTERNATIVE TO TSA SCANNERS: TSA SNIFFERS???

Seriously.

Here's an idea:

Instead of scanning people one-by-one to see if they're packing a bomb, why not instead sniff them a dozen at a time?

Then - if a sensitive sniffer senses a certain amount of PPM of any chemical associated with explosives, those people get closer scrutiny: either a thorough pat-down or a visual scanners.

It would be faster and expose more people to less radiation and fewer gropings.

All the TSA would need is a supplier of er um... let's say 15 x 15' sealed rooms with vacuum-sniffers to detect volatile chems' associated with explosives at the PPM level in a few minutes.

IS THIS POSSIBLE? FEASIBLE? PATENTABLE?

Lemme know in comments...
