Incidentally, the idea that a corrupt government would jug you to keep your testimony out of court forms the central theme of R.L. Stevenson's Catriona or David Balfour (same book, different titles in England and America). It's the sequel to Kidnapped, which is pure action adventure, but it's a political thriller with some adventure thrown in. A really good read.
You have far too optimistic a view of politicians and politics in general to suppose that they would not be willing to suspend habeas corpus to justify their ends.
Again, let’s stick to the available facts, not suppositions or assumptions.
It’s hardly a possibility limited to literature. If you are willing to allow the camel to stick his nose into your tent, do not be surprised when he bites you on the rump in return for your willingness to grant him the benefit of the doubt.
