Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
Sihali was acquitted of the charges in April 2005, but was re-arrested on 15 September 2005, and held as a terrorist suspect. He is acquitted and does not face deportation. This is the case of 'wrong place at the wrong time' situation or a case of looking for 'scapegoats'. [1]

Is the density of ricin so low that a pinhead-sized amount (I assume on the order of 10^-9 m^3) weighs only 0.5 mg? Or does this refer to a different delivery mechanism than injection or inhalation? "Ricin is 6 billion times more toxic than cyanide and 12 billion times more poisonous than rattlesnake venom by weight." This seems very unlikely.
