Manipulated Information from Government Possible in Society?

I totally believe that the government manipulating information is possible in our society. This is due to a point in which our society's government think that telling a particular truth to the public can be dangerous in terms of security, health, as well as themselves, etc. And to prevent that, the government might manipulate or not even mention the truth to their people in our society. I think of this as the government backstabbing me and the people of the society every time they lie or not mentioning the truth and killing us to death. But I doubt that the government will control or manipulate almost every information available to them. This is to the point in which the government don't want the public to notice that they are controlling information and tell most of the truth. Sure that most of the people of a particular society won't notice the lies but not a little percentage of that society. That is because I believe that there are at least somebody will eventually find out that the government is being corrupt of telling lies to the public and spread that message to every one living in that corrupt government. Then you notice that the government in which was telling lies to people about any topic has collapsed and went to extinction like the communist Soviet Union in the 1990's.
