Taika Seiyu Oyata had a deep respect for Law Enforcement and had a close friend on the police department who arranged for Taika to train the local officers near the end of the 1950's and through the 1960's while still living on Okinawa.

In the late 1970's, Shihan Michael G. Waddell was introduced to Taika Seiyu Oyata and Mike was a police officer with Liberty, MO at the time. Taika taught Shihan Waddell his Law Enforcement System and he began teaching it under the name Sundown Self-Defense Systems.

Tony K. Skeen trained in Shito-Ryu originally with Shihan Waddell and began training police with him around 1977. His father was an officer with Platte County. He joined Taika's organization in 1978 along with Shihan Waddell and learned Taika's system, thereby adding these new techniques to his training repertoire. 

In 1989 Lee Richards joined Shihan Michael G. Waddell and Tony K. Skeen at Sundown Self-Defense Systems and began teaching Law Enforcement courses. In 1992 Lee joined the Kansas City, Missouri Police Department where he began learning the N.L.E.T.C. systems as founded by Jim Lindell.  In 1998 Lee became a Missouri P.O.S.T. instructor through the Kansas City Regional Police Academy.
