That was probably in May 2002 on my second visit to Colombia, I was about to leave to Mexico.
I was called just before boarding the flight and suddenly found myself surrounded by policemen in rangers and weapons, a dog, a man shooting everything I was doing. They asked me to recognize my suitcase, open and empty it to show what I carried.
I had an awful time, 3 minutes in my life, where I was wondering what I could be carrying that would create so much trouble, how was jail in Colombia, what would happen to me, who to call?? it was so stressful
Eventually, they let me go, apparently, the tariff sheets were so thin that they were showing wrong on the control screens. I never took them along again
Such a stress!!
