re: #16 Charles Johnson
Ricin was used by the Bulgarian secret police to assassinate dissident Georgi Markov - they used a modified umbrella to inject him with a small pellet loaded with ricin.
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.
