The Denver Post reports that Saleman Abdirahman Dirie, who crossed the Canadian border into the United States, had about one pound of sodium cyanide in the hotel room, two miles from the Democrat Party Convention site, where he was found dead. (Hat tip: Charles Johnson.) That would be enough cyanide to kill hundreds of people. Odds are, this episode is the tip of a mass-casualty attack iceberg that may have derailed. Thank Heaven. Let's just hope that it is being pursued by counter-terrorism agents more vigorously than might appear from press reports.
