Nigeria facing another problem

Nigeria has almost won the war against boko haram, now they are up against another problem. Fulani herdsmen. They have been attacking villages, killing and maiming innocent citizens. Agatu, and now Nimbo in Enugu state. They are also involved in kidnapping. Evidence is the kidnapping of Olu Falae from his farm.
These men have become a menace to society.
This brings up a lot of questions, like, why are they killing innocent people. Wqho is arming them, because we know on their own they don't have the wherewithal to get such sophisticated weapons? What purpose do their financiers hope to achieve? Why are the northern governors defending them? It was the same scenario when boko haram started, the northern governors kept silent. Are there individuals trying to make sure this government does not succeed?
These are issues security agencies have to sort out before the situation escalates. The earlier they nip this in the bud the better.
