I have long wondered, do U.S. (and other major industrial) spies really use poison pills, in case they get caught? I know in the movies they are supposedly composed of cyanide. But I personally think ricin would be a better choice. What about non-industrial countries (assuming they have spies too)?
Is there any protocol on how they are to use these lethal pills? And have there been any reported cases in the news of this happening?
And furthermore, how do they get people to commit suicide on command? Most people, it would seem to me, would have an extreme aversion to that.
I think it was actually a pin, not a pill. And according to his autobiography, he was told that it was voluntary, in the event of torture, not to protect sensitive intelligence. To be fair, he had an incentive to say that whether it was true or not.
