The case of Raymond Davis[0] is probably the most mind-boggling in recent memory: A private contractor with a cover story as a cultural attache at the US embassy in Pakistan sees he's being followed by a couple guys on motorbikes while driving through Lahore, thinks he's going to get assassinated by Pakistani security forces, and shoots and kills both of them. He's arrested shortly thereafter with IR cameras, magazines full of bullets, and other espionage-related gear.
The US ultimately negotiated a payment to the families of the men Davis killed and secured his release.
