Thread: Aviation security retards ?!

So the good news is that I have had responses from Aviation security to my emails.
The reply is basically to throw Air NZ under the bus & state that empty ammo cartridges are defined as DG, there for they should be thrown out ???

So before I respond I'd like to get some more background to the AvSec process & DG classification.
Can any of you smart gentlemen who know something about airport and aviation security tell me
1. Who performs the inspection of checked baggage & decides what "ok" whats is not ?
Its my understanding from talking (many times to Air NZ staff) that the inspection, XRay etc of checked bags is carried out by AvSec staff and they alone decide what's good to fly or not

2. What is the classification of empty brass in Dangerous Goods ?
(an inert brass tube is "DG" ???? wtf????)
3. Why would empty brass be deemed different to loaded brass given both are packaged in the same manner and fall within the 5kg allowance ?
