However it outlines the entire screening procedure of international mail in Australia, and confirms that since 2002 100% of incoming international mail was subject to at a minimum one of the following screening techniques, however they could not maintain 100% and had to update their infrastructure in order to do so:*Canine sniffing for narcotics detection*Human inspection*X-ray scanning*Possible opening*Canine sniffing for the presence of vegetables etcWhat is happening is that they are running dogs up and down the conveyor belts or something similar. Which means the bottleneck is the quantity of correctly trained drug dogs, there really are not that many of them. Drug dogs are expensive, but the other techniques are even more expensive. So I expect they upgraded to postal intercept machines like the ion spec or something long since 2002, a decade is a long time. The key question then becomes the threshold at which the machines start to bleep.Also, lol at "canine sniffing for the pretense of vegetables", Australians! You guys! Always bringing humor to my day! :D
