Back in the period when my work office was near a mega-mega mall in downtown Ottawa, what must have been a similar bleach bomb went off in the mall's food court, detonated when someone opened the lid of an empty-your-tray disposal bin. Such is the power of money that almost no publicity resulted, I mean outside the various nearby government offices. Could have been a good thing since there was no repeat performance- but on the other hand you had to wonder if public safety was being ignored in the interest of shopping and the happy result merely an accidental byproduct.
