A 70-year-old American tourist killed his would-be mugger in Costa Rica earlier today.

The U.S. Army vet put one of the three knife-wielding attackers in a choke hold breaking his clavicle (and probably his neck) when the other (also seniors) tour members began fighting back the two other assailants fled the scene.

This is a great propaganda campaign for the Middle East: US Army, even our senior citizens will kick your Haji ass!
