There should be prosecutions for a number of people, perjury for starters. I don't know if the law of corporate manslaughter can extend to actions which drive innocent people to suicide, but if it does, then that is another ground for prosecutions.
I don't want more inquiries, I want people to face justice. Same as with Covid, involving the late Queen in an unlawful act, Grenfell, dumping sewage in rivers.
