Unshu classical bunkai is compared to street fighting emergency department & police statistics. An evidenced-based analysis (driven by data) allows one to create at least the following 4 categories of violence which may be relevant to karate-ka.
1. Male-on-male violence
2. Law enforcement (buncer/police) - which has different psychological considerations and physical relaities
3. Female domestic violence
4. Female violence derived related to a stranger attack
The aim is not to get away from classical karate, but given data is now available, to find the overlap of techniques which are both classical and practical based on statistics. The concept is represented in the below overlap diagram and is reviewed in detail in the book “Street Fighting Statistics & Medical Outcomes linked to Karate & Bunkai Selection”.
