Government beurocracies acting under the status quo will never reign this sort of abuse in of their own accord because doing so would be suicide for their own power. The exact same laws, precedents, etc that let CEOs not go to jail are leveraged to great extend by government agencies and the agents thereof so the government will never bring the cases needed to reverse the precedents. The solution must be legislative, so there must be public interest and political will that legislators seek to pander to. There isn't the interest or will to reign in the government, people want them to be able to ride roughshod over perceived wrongdoers. And there isn't political will to write legislation that has a double standard of formally exempting government activity. So the local minimum we're stuck in is that bad actors can "do whatever" as long as they do it as part of their day job and don't leave a flagrant paper trail.
