In Aftermath of Sydney Siege, Resources for Journalists

An Iranian-born gunman seized 17 hostages in a cafe in the heart of Australia's largest city Monday morning. The deadly siege ended 16 hours later with a barrage of gunfire that left two hostages and the gunman dead, four wounded, and a nation that has long prided itself on peace under pressure to explain why the shooter dropped from a government security watchlist.
