I read this AP dispatch quickly but it bothered me so I read it again, and then once more, carefully, and found what seemed to be a deliberate effort at misinformation. Let's look at the AP piece together. Even for those who read the entire text, the headline has a big impact. It lingers in the imagination, suggesting a certain tone, coloring the story. It suggests that people may be concerned but not terribly upset.
People generally read news stories to satisfy their curiosity.
The suggestion is false. Speakers particularly took police to task for their actions the night of Dec. 1 in the Capitol Hill neighborhood east of downtown - first for forcing demonstrators in that direction from downtown, and then taking aggressive actions that included firing tear gas and pepper spray. By using the inaccurate opening, the AP sends busy readers away with impressions diluted. Remember, readers tend to skim news articles, not study them. The contradictory impressions will tend to cancel.
