I read this story written by a journalist, so it must be true.
In Uganda, during the time of Amin, the journalist commuted into town each day by car. Each day, he was stopped at the same roadblock, asked to get out of the car and remove his shoes. Each day, the soldiers looked inside his shoes, then sent him on his way.
Being reasonably au-fait with Africa, he contained his curiosity, and did not ask what they expected to find in his shoes.
Until, eventually, his curiosity could be contained no longer, so he asked what it was they were looking for.
"Guns," he was told.
"How do you think I can hide guns in my shoes?" he asked.
"Dunno, but them's the orders. We have them written down."
"Can I see them?"
"Sure." The orders decreed that all vehicles must be stopped, and the boots searched for weapons.
For those who only speak Americanese, a boot on a car is what you would call a trunk, but there would be something lost in the translation.
