I was going thru the TSA scanner and as normal for me, ( Traveler every week) I have my hands swabbed and checked fro explosives.
Well the swab came Up RED and the army of agents decended on my saying they need to take me into a priovate screening area.
While in there they calibrated checked their machine and it was positive, they then did a re-swab of me and my pump and it came up Red again.
They wanted to me to then stip down, and when I ask why, they all clamed up and called for a supervisor that red me some US law of there right for a cavity search.
A second supervisor came in , and he had me wash my hands and then swabbed them and my pump separably and the pump was red and my hands green.
They then asked me to get a fresh insulin cartridge and they checked that and it was OK so they made me change it and then re-swabbed me in the normal way and I passed.
They confiscated in a sealed bag the old cartridge.
I was happy to get out of there (30 minutes) and glad that I pack extra cartriges for quick insertion.
The general agents actually did not know how to handle this case.
