Deadly antiques for sale on eBay

In a bizarre segue, Forbes.com has noted that although no one knows where Alexander Litvinenko's murderers got the Polonium 210 that killed him, other poisons may be bought on eBay:

Last year, Lee Cantrell, a toxicology professor at the University of California-San Diego, published a study in the Journal of Toxicology documenting 121 eBay auctions of poisons over a ten-month period from 2003 to 2004. Of Cantrell’s documented auctions, 24 involved strychnine, arsenic trioxide and other poisons considered by scientists to be "super toxic," meaning a dose of 5 milligrams or less would likely kill a human if ingested. The other 97 auctions in Cantrell’s study were for less toxic, though still potentially lethal, products such as mercury, antimony and thallium.

A search of items available today quickly turned up an antique strychnine bottle with "not much trace of residue" inside. Selling deadly poison under the guise of flogging collectables: one has to ask, are these sellers greedy or just incredibly stupid?
