Nah, not IMO. The video you linked to has the reporter claiming that the current state is "in stark contrast" to the day's earlier protests.
BTW, the term that I stated originally ("Mainstream media") may include CNN but it also includes AP, Reuters, and many more press agencies that are much more dignified. CNN used to be 'headline news' but has transformed into the same nonstop opinion shows in order to compete with Fox. So it's not the best source IMO.
But don't lose faith. Don't base things on the worst example. Instead judge Mainstream Media by the NYT, Washington Post, Reuters, NPR.
