That's funny, when I flew in LA from Bali, I got stuffed in a room for four hours because I had a rock in my suitcase.
Returning from Singapore I was asked if I had any "rare feathers"... I said no but was still taken aside and searched.
I like processing through Newark, New Jersey the best. They seem to have the least propensity for wasting your (their) time, or else a very good nose on who the actual problems are in the crowd and focusing their attention on them. [edit: and these use beagles to check luggage! How cute is that.]
LOL, what happened then?
There is only anticlimax :) The ‘executive’ screener was kindly about helping me sort them into a line of individual trays and then back into the luggage and didn’t show the slightest curiosity about any of it.
