Get me Jack Bauer!!!
But in all seriousness, this is a subject that hits close to home for me since I live near the border with Mexico and whenever I cross over there a kidnapping is a possibility. So whenever I cross, my wallet is empty except for my driver's license and some cash and I leave my cell phone back home too, that way if it happens they can't contact my family. If they ask me for their numbers, the only thing I know is "speed dial 1" or whatever. But in case of a kidnapping either one of those outfits would do, both have experience, SAS did the hostage rescue at the Iranian embassy back in the day, and Delta did rescue an American prisoner during the Panama invasion.
