re: #24 LWNJ
Ricin is very toxic when it’s injected. When it’s swallowed, not so much by far, and the damage is usually local and reparable. Good thing most non-pros do the research for their acts of heroism (///) from the movies.
It can be done, though.
There’s a case documented in the book Bitter Harvest by Ann Rule where a woman was convicted of attempted murder of her husband by ricin poisoning. It took them a while to figure out that that was actually going on and he came very close to dying. (She also killed two of their three children by burning down the house.)
