Anything of any real importance, E.g. evidence that implicates Mosad/Israel or still undisclosed blackmail material on current senior bureaucrats or members of the judiciary, will be withheld. They cannot resist the chance to use the weapon of the enemy, the "One Ring" as it were. They really should realize that it is not possible to wield that weapon without being utterly corrupted. The only thing to do is to expose it all, even if it seems like it will destroy the foundations of society as it stands. The reality is that the damage has already been done, but people are just pretending that there is any measure of legitimacy to it.
