CHOI!!! Be careful when you are dealing with Nigerians

I admit I don't really know how true this is o, so I will just say it the way I saw it. Though it has been an interesting topic on twitter. Some people allege that President Goodluck Jonathan wore a bullet-proof vest when he visited Borno state recently.It may be true anyways. If it's true the question is, what is he really scared of?
