New Assault Studies Ready for Publication

The Force Science Institute has completed three new studies on the speed and movements associated with armed assaults. Dr. Bill Lewinski explained: “The goal of our research was to obtain highly accurate measurements to further explore the findings of our earlier studies. Where we once measured movement speeds in the hundredths of a second, we...

Doubts Raised About Certain Reaction-Time Training Exercises

Are some training exercises that focus on reaction time unintentionally compromising officer safety on the street? Two instructors raised that concern recently in separate presentations at the annual conference of the International Law Enforcement Educators & Trainers Assn. (ILEETA). Larry Hahn, a certified Force Science Analyst, told of detecting what seem to be unnaturally slow...

Citizens Academy With A Twist Puts Civilians In The OIS Hot Seat

The dominant goal of citizen police academy programs is to get civilians to walk a mile in an officer’s boots. Thanks to the creativity of Force Science Analyst Steven Goard, those who attend the academy conducted by the Livermore (CA) PD walk an important extra mile—through the landmines of a simulated OIS investigation that tests...
