What’s legal for an intelligence officer and what isn’t is usually separated by a national border. The very nature of being an espionage officer makes you illegal in other countries—although perfectly legal in your own. Spies never lose the feeling of constantly Walking the Edge. And they know that if they are captured, they will face prosecution in the host country, not their own. While their country may suffer embarrassment and diplomatic consequences, it is the officer who will end up paying the ultimate price. The best outcome is prison; the worst, a trip to the gallows.
