im convinced that its a fabricated story, serin osman is the new head of oni and she already has palmer trying to kill halsey, the reason for the cover up is because oni already went public with some parts of the spartan ii program and they cant afford to let the public find out that they ran off with 75 six year old children to make supersoldiers, they cant afford that because right behind that mystery is the hundreds of other children they kidnapped to make the spartan iii's, they are just desperately trying to cover their asses since things like that are how governments are uprooted
