Terrorists usually have a cause. You may not agree with their cause but they have it, and it drives them to attack much stronger forces, take crazy risks and sometimes deliberately kill themselves with intention to inflict some damage, however relatively small, as suicide bombers.
Many of us never dreamt remotely that we would live long enough to see terrorists without a cause emerging amidst us. But here we are, at least in Uganda, with acts of terror without a cause manifesting frequently. A fortnight or so ago, a man drove a bus full of schoolchildren into the path of a moving train. Because there was no barrier at the railway crossing, a human signaller stood in the road and waved vehicles to stop, even as the powerful lights of the train were on, that morning and the sharp, loud hoot could be heard a mile away. The bus driver insisted on disputing the small space with the train, which hit the rear of the vehicle, throwing it onto the ground, where death occurred.
