One story I heard during my instructors' course was that of a prominent Israeli Judo practitioner (olympic level possibly) was once introduced to the style of Krav Maga. He was very excited about it to say the least. Especially the gun defenses. So he goes and demonstrate these techniques to his students. With a real gun. Which was loaded.
He's still alive, but man, what an idiot.
