Sifu Derek Johnson is a kung fu instructor of the Jow Ga system, former marine, and retired law enforcement officer.  For over 25 years, he served in numerous law enforcement specialties.  He was assigned to many agencies in Washington D.C. and Baltimore, such as: violent crimes, undercover narcotics, community outreach, leadership as a Patrol Commander, internal affairs, and worked with the DEA and FBI departments.  I have been outraged for the families that have lost loved ones to senseless shootings, and wonder why is this happening?  Do officers need more training or stricter screening and guidelines?  What is the problem?  Derek sheds light on the training many law enforcement officers receive and what can be going through their minds in these high stakes situations.  He also shares my frustration, and speaks openly as both a black American and a law enforcement officer on the Black Lives Matter movement.  I strongly believe in the movement and was grateful that Derek was so open with me on this sensitive subject.  I also wanted to understand the protocol for officers in aggressive situations, and what we can do to help change the perception of law enforcement officers in the community.
