EP53 ‘How Much Time do You Have? Understanding Knife Attack Dynamics’ with Dr. Michael Kantor
Description
Summary:
This insightful conversation on the Trainers Bullpen delves into the most recent critical research on knife attacks, particularly focusing on the dynamics of close-range concealed knife assaults and their implications for law enforcement training. Dr. Michael Kantor discusses the study he and colleagues conducted - 'Close Quarter Concealed Knife Attacks: How Much Time Do You Have? which was published in Police journal: Theory, Practice and Principles in 2025. This important study examines the speed and effectiveness of knife attacks, the importance of understanding attack distances, and the types of knife attack biomechanics and their effect on lethality. The findings highlight the need for law enforcement to adapt their training to better prepare for the rapid nature of these threats, emphasizing the significance of concealment, the close distance, and the speed of response.
Takeaways:
• The average attack time for concealed knife attacks from 8 feet is about 1.4 seconds. The fastest person in the study completed the attack in 1 second.
• Males are significantly faster than females in executing knife attacks.
• The thrust attack is the fastest and most lethal method of knife assault.
• Concealment of the knife changes the dynamics of the attack significantly.
• Training should simulate real-world scenarios to prepare officers effectively.
• The 21-foot rule may not fully represent the dynamics of knife attacks.
• Understanding the time it takes to respond is crucial for law enforcement training.
• Knife attacks can occur within five to six feet, often within the first step.
• The act of concealment is a critical factor in the timing of knife attacks.
