Venezuela has earned a CPI score of 1.9 and are ranked 172nd out of 182 countries of the world. The event that kicked off the country's slide in to corruption was the discovery of vast amounts of oil and by the time the '70s decade arrived, the Venezuelans had started calling the petroleum being mined as ”the Devil's excrement”.
Hugo Chavez came by in 1999 promising to remove corruption but did nothing to even slow it down as his movement was accused of the same ills as the movement before him; ills such as political patronage, cronyism, and of course, corruption.
In Venezuela, even the police, the department appointed to protect the law, are notorious for their corruption and bribery.
