Pita Driti was unhappy with Aiyaz Khaiyum and Frank Bainimarama and so was Mohammed Aziz but they couldn't talk to each other about it. They always brought this up when Ratu Ului Mara met them separately so he (Ratu Ului) told them individually to go and talk to each other, which they did and the rest is history now.
About the weapons at GPH, there was a Company strength of 120 men at GPH at any one time so they had their personal weapons with them all the time. Unaccounted weapons from where? Only weapons left in Fiji now are at QEB.
So this is the same scenario that Bainimarama was going through in 2004-2006 before he decided to overthrow the legal Qarase government because they were going to charge him for the same charges that Driti faced and has now been convicted and locked away, waiting sentencing on 10 December.
