The Answer:- The Newspapers. And because it's in the Newspaper it doesn't make it true, and if a story has an element of truth, it's because it's usually largely exaggerated.
The Rebel.
That is an extremely true statement, I personally have not purchased a newspaper for any reason other then advertisements in more then 30 years. I lived in Washington DC for 50 years, there is one National Park you see in pictures all the time it is a straight shot. All grass nothing but grass very well maintained and kept cleaned every day and night by the United States Park Service. You will see their people there all the time cleaning. My estranged husband and many of my friends are now retired but at the time were United States Park Police Officers. One particular day a demonstration went bad and the demonstrators according to the printed media and the TV media "picked up what was available to defend themselves against the police" . What they found in this very clean Grass park to us 4 X 4 with spikes nailed through them. More then a dozen officers were hospitalized and out of work for some time due to their injuries. Newspaper nor the media NEVER told that part of the story nor the Officer's horse that was injuried. They only talked about the undue force the officers took trying to break up the fighting between the different protesters. Oh and no one was shot that day.
