One extremely contemporary example of this is Hong Kong. In trying to find out what was going on, I was searching for videos of the police shootings. This [1] is the US cut of the first shooting. This [2] is footage of the exact same incident from ChannelNewsAsia, a Singapore news company. No need for commentary beyond that since I think the extreme difference between the videos, and the message they try to convey, speak for themselves.
I'd never heard of CNA before that. Seems to be quite a solid source of information [3]. Though I expect it may only a matter of time before that honeymoon fades. It wasn't long ago that I also used to think the same of Reuters.

"Police confirmed that an officer opened fire at a protester, saying he was acting in self-defense. “A large group of rioters was attacking police officers in Tsuen Wan,” police said in a statement. “Police officers warned them, but they were still attacking police. A police officer’s life was seriously endangered. In order to save his and other officers’ lives, they fired at the attacker.” One clip posted on social media and verified by Reuters shows the protester, an as yet unnamed 18-year-old man, swing a baton at a policeman, brushing his right arm."
The article and video are designed to imply that the Chinese are claiming that the the officer who fired at the protester is the one who's life was in danger -- that brushing the officer's arm was placing his life in danger. Somebody only consuming that media would have no idea that in the middle of the group of protesters was a police officer who the protesters continued to beat, potentially to death. Note as the crowd disperses to the point that the beaten police officer laying on the ground would become visible, the video immediately cuts to a new frame - repeatedly.
This deception is made even more gratuitous by the inclusion of the police spokesperson's response. Without being able to understand the context of what was happening in that video, which is not provided, the spokesperson's comments sound completely absurd and basically like he's just overtly lying to justify shooting a protester. That in effect makes people think the officer's statement is simply propaganda. Somewhat ironic.
I think the whole propaganda war is idiotic. Let people see what's happening on both sides with complete context and judge for themselves. Real life is not full of Hollywood heroes and villains, it's invariably a million shades of gray. Debate and discussion these issues is healthy and productive for everybody. Most ironically, I suspect people would ultimately come to the same conclusion even with honest context. So why lie?
