Good ideas from gava but "they" (the section of elected thieves who invested/gambled a lot of their own money 'sportpesa' style in politics to eat, heavily armed tenderprenuers e.t.c) will obviously use corrupt Judges to block the polygraph test, and perhaps even the importation of polygraphs and demand the money to go to their salaries, they are opportunist, otherwise they work very well in catching thieves elsewhere
