Suicide weapons, easily concealable and
quickly lethal, were developed as a last
resort should capture become inevitable.
Fast-acting poisons that killed within
seconds could be delivered in the form
of a capsule, a glass ampule full of
liquid poison, or a poison-tipped pin.
Suicide weapons are a less-than-perfect
defense and are only as effective as the
resolve of the operative; at the show
trial of downed U.S. pilot Francis Gary Powers, his poison pin was
on display, debunking the U.S. claim that his was a weather flight.
