Does it? I mean if the coverup becomes proven in criminal court, then are they still protected? I thought the problem with coverups is that they are very hard to prove, and when some of them eventually get uncovered, then the department simply treats it as some small irrelevant internal affair. Hence legally QI still stands. Though of course it's strange that these half admissions of coverups are not treated sufficiently seriously by the courts.
