Apologies as I wasn’t even sure if it was a bug originally, so I didn’t report it (until now). I considered it possible that was intentional design. I have since reported it under Claim #ACEO-21528. I’ll include all my relevant pictures here, as well, to detail what I’ve encountered. Though this is just one example - I’ve had the same problems at a different airport, as well.
First here I’ve included my overall baggage layout. I added arrows so you could get a sense of movement. My check-in areas merge to the central scanning area, shown here, which includes nearby break rooms for security staff only and a restroom. Security operates on a one-hour shift.
Next you can see an example of a suspicious or rather scanned contraband bag that has been cleared by this security staff to make it to the plane. We can see it is clearly guns that have made it beyond the manual scanning machine.
This is from an unrelated incident, but nonetheless shows that other packages have indeed been cleared despite the security setup and function.
Finally we have the actual notice that suspicious items have made it onto planes at my airport despite my best efforts.
If there’s anything else you needed, please let me know. I was hoping this would give a good overview of what I’ve experienced.
