We handle this problem by creating the page as a news stream, based on each individual news event. We don't have UK riots yet, but here's an equivalent. http://newslines.org/michael-brown/ Unlike Wikipedia's static page-based format, because each news item is discrete, readers can sort the line from oldest news to first, or vice versa. We also use video and other embedded media to tell the story of events, unlike Wikipedia's textbook-like pages.
