RJ White, despite being a 9th dan and co-founder of the internationally successful martial-art Bat-Jitsu (the meld of Ju-Jitsu and Baseball), is a pacifist and only beats the crap out of people that really deserve it.
RJ (Registered Jack) is registered with various law enforcement
and military organisations for his skills at being able to kill
with his left eyebrow. Whenever a homicide is committed using the
left eyebrow technique, RJ is brought in as both a consultant, and suspect.
'Registered' is an honourific title, not his first-name.
If you don't believe him, then you don't know Jack.
RJ has a Bachelor of Mathematics from the University of Waterloo, and a Bachelor of Universal Madness from the University of Leigh (Instruments).
