These things are not humans but human eaters. I have not seen or heard such misterious action in my life before. There is no human in his right senses that can act like this?
The Nigeria government have to be blame for such act because Nigerians are not protected by the so call government. Police are not given the support needed to do their work. Every other country in the world, one or two firearm to a cop but Nigeria want the police to fight crime without arms, without good road, good cars and without good salary.
Does the government have to do everything for their own interest alone? Why don't they sometimes think for the ordinary people.
Whatever you are doing will come back to you someday, sometime.
