Wringing out the words, we find this: "We are very confident it does not appear to be dangerous."
You know what just occured to me: How does anyone know that sarin gas smells like almonds?
well, I'm VERY CONFIDENT that if this isn't something to be concerned about, al-quaeda is taking serious notes on the reaction and the cluelessness* of those involved regarding the origination of this odor..
I sincerely, sincerely hope they don't leave it at "it's not dangerous" and find the source..
*this isn't a slam at those attempting to find the source, just that no one has a clue what it is and where it's coming from..
