Over the last year, nearly 2,000 police officers in Colombia have undergone lie-detector tests in a bid to root out corruption in the country’s police force. Of that total, 434 police were found to have “affected the transparency of the police institution,” according to the Colombian authorities.
“Lie-detector tests have become an efficient tool that provide credibility and confidence and protect this institution ...,” Colombia’s defence minister, Rodrigo Rivera, said earlier this week.
Across Latin America, particularly in Mexico and Ecuador, lie-detector tests are commonly used to combat graft in the police force.
