Non-dangerous dangerous chemicals.
Al-Reuters: “United Nations officials found vials of dangerous chemicals, which had been removed from Iraq a decade ago, in a UN building in New York, but UN officials said on Thursday there was no danger.”
Whoops: al-Reuters just revised that to “vials of a chemical warfare agent.” That’s some fine editing there. In the future, they might want to try editing before posting online, but that’s their business.
