Be careful what you ask for
The Colombian military took out FARC #2 Mono Jojoy by giving him a pair of boots with a GPS chip hidden inside them!
This is real, people, not an episode of "Chuck".
El Mono was diabetic and had sore feet. The government intercepted a radio message from the jungle ordering special footwear and filled that order for him, and the rest is history.
The CIA sure has come a long way from when they tried to off Castro with exploding cigars!
