BY KORIR JUMA,NAIROBI,2ND JUNE,2018-As  all eyes  get ready for planned  fresh vetting for procurement heads of government institutions as per president Kenyatta’s madaraka day announcement,  the use of   complete  polygraph tests to conduct the same may proof a hard nut to crack going by the sentiments that have followed.Kenyans and several leaders  have cast aspersions on just how the exercise will sail through.

Among the leaders who have expressed doubts  is Senate Minority Whip Mutula Kilonzo Junior who says currently  there is no law that supports use of Polygraph test  which may mean that  we must have changes   in law  to anchor lie detector tests in anti-graft statutes.

While announcing the fresh vetting exercise at Madaraka Day celebrations in Meru on Friday, President Kenyatta ordered that the exercise is concluded before the start of the 2018/2019 Financial Year.

“All heads of procurement and accounts in government ministries, departments, agencies, and parastatals will undergo fresh vetting, including polygraph testing, to determine their integrity and suitability,” President Kenyatta said.

Lie detectors rely on several physiological indices including the subject’s pulse, blood pressure, respiration and shin conductibility during interrogations.

The physiological indices are usually captured graphically thorough sensors attached to the body of the person being interrogated.

Under the technology, lies are usually detected through heightened nervousness. The person being interrogated is presumed to be telling the truth if they remain calm in the course of an examination.

The use of lie detectors is popular in the United States where federal law enforcement agencies such as the Federal Bureau of Investigations, National Security Agency, and the Central Intelligence Agency use polygraphs to detect lies.
