Unbelievable.
At the SCI (Safari Club International) convention in Reno this year TSA was using the new gunpowder residue sniffer machines. With most of the gun dealers and hunt exhibitors leaving Sunday it was a LONG painful line.
Those sniffers don't detect squat they are "probable cause" generators........if the rental wannabe doesn't like the look of ya they trip it........then detail search based on that.
I was at Sandia Labs when those were first being pushed on our EOD teams as explosive sniffers. They didn't work then, later or even years later well enough to depend on.
If it wasn't a certified explosive detector dog's snoot that picked up the scent then it is a PC generator....nothing more.
Hope yer doing well 17.......ain't seen ya around for awhile. Stay Safe !
