CEPS and Corruption in Ghana: Where Does the Buck Stop?

There are custom officers who own 13 cars  and 5 houses in Koforidua. Corruption at CEPS is runs deep from the head to the bottom. The head of the commission of CEPS is corrupt. The police is corrupt. The Accountant General's department is one of the most corrupt institution in the country. Do anyone knows any institution in Ghana that is not corrupt? I am struggling to find one.
