"“The atmosphere was extremely intimidating,” the Lancaster University student said. “People stared at us all the time and men would come up to me and stroke my stomach and bottom. They would also say horrible, suggestive things. The worst time came when there was a rumour that a white man had raped a black woman. We were scared that we would be raped, robbed, or both. People were arguing, fighting and being arrested all the time.”
The “internationals”, as the army labelled the stranded tourists, were among the few white people in the stadium. Marked out by their skin colour and unfamiliar accents, they were verbally abused, while their luggage made them targets for robbery. "
Minority were armed. Minority were leaders of gangs and therefore those with the strongest personalities and aura of power. And they enjoyed wielding it.

They did not want to get their Arse shot at or stabbed.
