Why no justice for the corrupt DA?

He didn't do anything illegal. He just didn't push too hard and accepted everything that was handed to him (unethical, yes, but not illegal).

In my opinion, Eckstrom was simply incompetent and in way over his head. He was spoon fed data which made it appear he could get a quick conviction in the trial of the century.

It was not up to the tribunal to judge and punish Ekstrom's actions, so they had nothing to do with it. He probably did get some punishment, specially because everyone in the Cabinet from the PM and down were involved in promoting the investigation.
