Anti Corruption Commission cant be effective without a big change in the government. Rulers of third world countries thrive on corrupt systems. They can bribe themselves in and out of almost anything.
Corrupt politicians can buy their votes on the way to the parliament. They can infulence judicial decisions in their favor. They can manipulate police, law makers and media in a way that protects their non corruptible image in front of public (voters). What can one realy expect from corruption busters when their employers are those same direct beneficiaries of corruption?
