Saw this in my level 1 tactical knife class. We were discussing the Tueller Drill and reaction time. BTW the FBI pushed the distance back from 7m to 10m. The whole discussion of reaction time explains a lot such as why you can watch yourself locking your keys in your car and understand how you couldn’t stop. Distance is your friend and always follow Gibbs’ rule #9.
Gibbs & Kate (in unison): "Never go anywhere without a knife."
