Over $380 billion missing in Nigeria

From the BBC:

More than $380bn has either been stolen or wasted by Nigerian governments since independence in 1960, the chief corruption fighter has said.
Nuhu Ribadu told the BBC that Nigeria has "nothing much" to show for the missing money.
He said the worst period for corruption was the 1980s and '90s, but currently two-thirds of governors are being investigated by Mr Ribadu's agency.
Nigeria is Africa's biggest oil exporter but most people are poor.
The country is regularly ranked as one of the most corrupt by graft watchdog transparency International.
President Olusegun Obasanjo declared a state of emergency in Ekiti State on Thursday after the governor was found guilty of siphoning state funds into personal bank accounts and receiving kickbacks.
