NAIROBI, Kenya (AP) — David Odhiambo was one of the blue-uniformed security guards tasked with protecting Nairobi’s Westgate Mall one year ago when four heavily armed terrorists attacked. The work David was paid to do — search purses and bags, mostly — earned him two bullets in the head, injuries that cost him his job.

Nairobi has tens of thousands of guards like Odhiambo. They guard banks, restaurants, malls and homes. They aren’t armed and when criminals or terrorists attack, they are often the first casualties. Two bullets fired by al-Shabab’s four mall attackers grazed Odhimabo’s scalp. At least 67 people died in the assault on Sept. 21, 2013.
