Who would've thought that buying a concentrated spray of chemicals from Walmart and then proceeding to fill your home with it was a bad idea?
'It's sold in Wal-Mart, in America, it _must_ be safe!'
'It's sold in Wal-Mart, in America, it _must_ be safe!'
Actually, this is a pretty reasonable heuristic. If this happened in India, say, then the story would have been very different. American regulatory institutions are relied upon by the whole world, and are de-facto global regulatory institutions. Examples include the FAA, the FCC, the FDA, the NHTSA, the CDC (which has lost a lot of credibility in this pandemic), and so on.
Except apparently in this case, eh?
