That’s Maori Priest Irrarangi Tiakiawa, keeper of secret Maori martial arts techniques, including death strokes:
“I think this (death point striking) art should die. It is too evil for today’s society. I once witnessed my grandfather having an argument with another man and the other man was in the wrong, so my grandfather just got up and struck him with one finger to one point and the man died… “
The interview is interesting, and includes what to do if confronted by a Maori showing his war face:
1. Stand still. If you run you’re gonna get hurt.
2. The warrior will likely throw something down in front of you. If you don’t pick it up and hand it back to him you’re gonna get hurt.
3. Don’t fight. If you do you’re gonna get killed.
Fortunately, you’re unlikely to encounter a Maori warrior unless you’re in New Zealand, but now you know how to react and you can live to enjoy another day of awesome.
