This is one of the bigg(er) miscarriages of justice in this country, and touches many aspects of how our world works - the government, the legal system, the duties of companies to behave ethically vs. contractual requirements. Even PFI deals. None of this is entertainment except in the sense that the "entertainment" gives a sense of levity to be able to keep going in the face of the awful misery that this deadly entanglement of failures caused - early deaths, whether by suicide or just human misery, lives ruined through multiple generations, etc.
Whether you're a lawyer, work in business, own a business, are a voter in this country or are just a member of the public, all of these things are very relevant to how the system works (or doesn't).
It was caused by people not paying attention, being professionally incurious, or refusing to "see" what was in front of their faces. We should ALL be paying attention.
