Because of the new technologies, we are entering an age where it will be impossible to conceal wrongdoing. The recent incident of journalist Jamal Khashoggi being killed and 'disappeared' by the Saudis is an example. They thought they could remove him from the world and no-one would ever find out what really happened. But the incident was recorded by a technology which cannot be divulged. I don't think any government will ever attempt to pull a stunt like that again.
