I recently returned from Kiev to New York with an all day stop over in Amsterdam. I bought some perfume in the duty free shop for my wife before I left Schipol to visit Amsterdam for the day. It was sealed in a plastic bag  Now I know most airport security procedures are in place to allay the fears of the general public rather than to actually catch terrorists, but this plastic bag deal got me thinking. What if I was a terrorist? In that case I would buy two or more bottles of wine have them dutifully sealed in plastic bags and proceed to my lair in Amsterdam. Using a hypodermic needle I would suck the wine out of the bottles and replace it with the bomb material, one component in each bottle. I would use wine since the cork would allow me to do this. I would return in the evening for my flight to New York confident in the knowledge that no security inspector would ever notice the tiny holes in the plastic bag
