My brother-in-law took Taekwondo in the 70s. His master was from Korea and at the top of his organization in rank. His first lesson to new students was to show the bullet hole in his knee that he got in Seoul trying to kick a gun out of a robber’s hand.
I studied martial arts with Gerorge Dillman in Reading Pennsylvania back in the 1970's. During that time he confronted a robber, but George rather than using his martial arts skills, used a shotgun to confront the robber. He took quite a bit of razzing for that!!
George Dillman, 10th Degree Black Belt, began serious martial arts training in 1961 with Harry G. Smith. He went on to study with Daniel K. Pai, Robert Trias, Seiyu Oyata, Hohan Soken, Wally Jay, Bruce Lee and Muhammad Ali. Official Karate magazine (Nov. 1982) described Dillman as "one of the winningest competitors karate has ever known." Dillman was four-times National Karate Champion (1969–1972) and during this period was consistently ranked among the top ten competitors in the nation by major karate magazines. During his nine-year competitive career, Dillman claimed a total of 327 trophies in fighting, forms, breaking and weapons. In 1997, George Dillman was named Black Belt Magazine's Instructor of the Year.
