Now I remember this was the brown pellet story that was on this bus in Vancouver. There are media reports about it.Of course they wrote it off as not terrorism.
I hadn't heard about this so googled it...

>>Police believe the substance may be a gas called phosphine, which is an industrial gas used as an insecticide and for pest control.<<
If it was not terrorism, what a friendly neighborly type? Pshaw!
Any links on this story Gal?
