Until the mass-internet made this possible, governments actually got away with it pretty much all the time. In some cases we got to know decades later, as documents were declassified or people confessed on their deathbeds. In most cases, we likely never got the truth. That's really not possible now, as long the internet stays up.
(Also, big shout out to FOIA laws. With all their limitations and imperfections, they were a massive step forward towards transparency in government. They would arguably have become a historical necessity at some point, but the anglosphere - Clinton, Blair - was definitely at the forefront of that shift.)
