Were these the unlucky sods who were executed by Al-Shabaab for spying?
Anyhoo, no need for the video. Recruitment of informants and infiltration of organised groups operates on very basic principles i.e.
1.
Money -Chedda, mullah, dough, bread, chapaa...... (No need to say more, check the flow). People will willingly sell their mother for the right price. Just look at Rt. Hon. Tinga Agwambo for instance.
2.
Ideology: Hii ni ile you prey on a person's vulnerability with regards to political, social or religious beliefs i.e.identity based recruitment. Hapo ndiyo utapata feminazis, social justice warriors, environmentalists, NASA and Jubilee supporters, white supremacists, anarchists, Islamists, Mungiki, you name it.
There're a few wadau hapa Kenyatalk in this category, na si wanajijua?????

3.
Coercion: Hii ni basically ku threaten kufinya mtu makende if they don't compromise. Also you can employ blackmail a.k.a "honeypot" Unatumia kunguru, ana seduce your target, wanaenda lodging iko na cameras, jamaa ana kula vitu and voila!!! Si unakumbuka saga ya Kirinyaga Deputy Governor? Kitu ka iyo but more professional. Kwanza the best ni ile you entrap msee with a homosexual alafu you record him. He will bend to your will like a puppet.
90% of wadau hapa Kenyatalk wako in this category 

4.
Ego: Hapa, you rely on basic human nature. Some people love a sense of self importance. Ama unatafuta a bored housewife with access to info alafu una seduce yeye na kumpatia an exciting life ya tradecraft na good sex kwa private villa kule Watamu ama Dubai. Pea yeye excitement ile hajawai ona! Basically, give disulioned / bored / egoistic people a sense of heightened self worth.
