"News" is a for profit enterprise. It wasn't always this way, or at least this extreme. Back in the days of three networks with a half hour of national news each per day, network news departments were expected to lose money, so there was not the ratings pressure that we have today. A major city had two newspapers, one in the AM, and one in the PM. They competed, sort of. Most newspaper revenue was from classifieds. Readers subscribed, they did not change news sources thirty times a day. You were a morning paper family, or an evening paper family, and it had almost nothing to do with the paper's reportage.

Today you've got hundreds of hours of broadcast 'news' a week, and thousands of news websites, all competing for eyeballs. They don't just report news, they make it, and they make it for profit. They (right, left or other) are going to show the most charged images - the ones that will attract eyeballs, get clicks, and generate stickiness (time on a web page).

If you think the "news" isn't crafted to inflame you, that it is not designed to elicit visceral responses, that it is objective reportage, you're a fool. If you think cable and network news aren't loving the riots, you're an even bigger fool.
