Recently, we had a conversation about the challenges of managing immigration in our country, and touched on the activities of organisations such as Operation Dudula, which campaign to give priority to South Africans when it comes to job and business opportunities.

Dudula is again in the news, following the arrest of its leader, Nhlanhla 'Lux' Dlamini.

his week, we ask whether there is a leadership vacuum in our society, which leaves space for groups like Dudula to flourish. Are vigilantly groups necessary to enforce the law in SA? What dangers accompany vigilantism? What is the difference between citizen policing or a citizens arrest and what Operation Dudula has been doing?
