All governments have dirty hands and nasty little secrets. They normally perform more efficiently to keep them well buried.

For example:David-Kelly-post-mortem-kept-secret-70-years
"weapons inspector Dr David Kelly will be kept under wraps for up to 70 years. In a draconian – and highly unusual – order, Lord Hutton, the peer who chaired the controversial inquiry into the Dr Kelly scandal, has secretly barred the release of all medical records, including the results of the post mortem,"

Definitely dirty hands and a secret to bury there Methinks!
