Evidence

In these operations Fitzpatrick rounded up large herds of camels from the nomads, and he also withheld the salaries of the chiefs in area, who were employees of the state. Such collective penalties continued, although the commander, Collinwood, stationed in Qabridahare, had already punished the community for the same “crimes.” — Abdi Ismail Samatar, Africa’s First Democrats, 200
