On a recent trip, a young man with an AK-47 boarded the noisy bus and prodded the barrel of his assault rifle into the belly of a middle-aged woman. Rather than panic and scream, she politely asked him to refrain, and the young man, a soldier in the Sri Lankan army, looked a bit embarrassed and apologised. The weapon,Michael Kors, hanging from his shoulder, had accidentally prodded the woman as he leaned forward to stow his luggage in the cramped overhead compartment.
