airport backscatter machine trips on gsr
#1
I recently got my kid sister into home defense. she took the plunge and bought a 12 ga pump action. she's been to the range twice now learning how to fire it.

right after her second range trip, she went to work as a bartender, went home, and woke at noon to be picked up by me so I could take her to the airport.

as she went through security, apparently, the computer panel alerted the screening agent to chemical check her left arm. she fired no more than 15 rounds the previous day.

just thought I would pass this on.

I've often wondered about this. Thanks for the confirmation, good to know.

Backscatter machines are no longer in use at airports. They were recently removed due to the manufacturer not being able to outfit them with privacy software. Millimeter wave AIT units, however, are in use at many airports. Neither the Backscatter or Millimeter wave units "trip on gsr" or any other chemical or explosive agent. They detect the presence of metallic and nonmetallic threats (guns, knives, blocks of C4).

What likely happened during your sister's security screening, is that she entered the body scanner and the machine detected an anomaly. Perhaps a watch or bracelet on her left arm? The agent conducted a visual check of the item on her arm and elected to perform an ETD (Explosive Trace Detection) swab on her arm. The ETD machine that the swab was fed into alarmed for gun powder or some other chemical.

The agent could have also just decided to conduct the ETD check randomly and either blamed the AIT machine or led her to believe it was the AIT machine that caused it to avoid going through a more detailed explanation. (Not that I agree with doing that, but it's possible.) There is currently no body scanner or Metal Detector in use that can detect explosive or chemical residue.

It's not my intention to turn this thread into a debate on the pro's and con's of body scanners, airport security, TSA, DHS, WAWA vs Sheetz, Geno's vs Pat's or anything else that can be debated.
I just thought that I'd take a couple of minutes to clear up some possible confusion as to what body scanners and airport security equipment can and can not do, so that further mis-information is not spread.
Just like many of us pro 2A folks spend time correcting many of the things that the Anti-gun people say and publish, I read this thread and saw that something just wasn't quite right and figured I would try to set the record somewhat straight.

It could have been the range trip, but then, it could have just been a coincidence. I've been pulled out of line to have one arm checked as well, but it was "just because", I guess. It was before I even started going to the range.

I've also randomly had other things bomb checked, like a reading light.....

Nothing like that has ever happened to me. I've had them swab my stuff the day after I was shooting the the morning of me cleaning spent casings and unburnt powder our of my luggage items with no probable cause. And they came up clean. I've also gone through the old "blow job" chamber surely covered with whatever and nothing happened.

this very well could be the case. i'll ask her tomorrow for specifics. she called to tell me about this when she boarded the plane and she was getting pretty upset when i started grilling her. i gave her my spiel about opt-ing out and what not and she cut the conversation short.

As someone who flies a lot I think I'll start taking baths in Hoppes no. 9 before I leave on trips. I'll be Bannana-smelling-chemical-fresh all the way to Taiwan! Big Grin I'll be high as a kite, likely with permanent brain damage, but at least I won't get on the no-fly list by accident!

Backscatter machines are not made to trip on munitions residues.

Probably another type of sniffer devise did it.
