The reactionary gap drill is associated with which officer?

• A. Lt. Dennis Tueller
• B. Sgt. James Carter
• C. Officer Maria Chen
• D. Constable Ana Ruiz

Answer: (A)

The concept being tested is how much distance is needed to recognize a threat, decide to act, and begin a response before an aggressor can reach you. This idea comes from Lt. Dennis Tueller, who studied response times and demonstrated that an armed suspect within about 21 feet can reach an officer faster than the officer can draw and fire. That work gave rise to the term “reactionary gap” and the practical guideline often cited in training to keep a safe distance during confrontations. The other names listed aren’t linked to this specific drill, so the officer most closely associated with it is the one who conducted that influential study.
