So what does TSA do these days if an object -- e.g., a bottle or bag of breast milk -- alarms the ETD? In addition to the inevitable extensive property and personal search, is the specific object automatically banned regardless of what it is?
Even if it's obviously food for a baby? That's what this case sounds like, and they even refused to let the kid drink it on the spot.
Or something else medically necessary? Or a $1000+ laptop?
That seems like one of the root problems here -- TSA/TSOs don't seem to understand that the ETD technology should be an input for where to look for issues, not a black-and-white determination if something should be confiscated.
