More than anything else the breaking point and most fatal mistake of the North in over-testing Yorubas was attacking Yorubas in Ibadan which proved fatal. I'm an Igbo boy born and raised in Ibadan, and I know enough not to mess with Ibadan people...Ibadan is the beehive of Yoruba militancy and ruthlessness... all the most violent street thugs, street fighters, vigilantes etc you can find in the SW are headquartered in Ibadan. I witness lots of ethnic violence when growing up in Ibadan - especially Sango and Beere axis), and the brutality of the killings alone was scarring reminiscence for me.

Ibadan is the South East equivalence of Aba or Onitsha when it comes to having no joy, that's why Hausas can do nonsense anywhere in the East and maybe get away with it... but in Aba and Onitsha? it will be a Slaughter house for them.
