High Definition Scanning (HDS)

We use the latest LIDAR technology from Leica and Faro to accurately map incident scenes for documenting evidence and for measuring bullet trajectories. The data captured from these instruments can place the viewer in the scene from any prospective making them invaluable tools for crime scene reconstruction. We have also used UAS (drones) to supplement the capture of land based point cloud data.

TASER Flammability-Revisted

In 2004, Wyant was part of an extensive study that evaluated the flammability potential when OC sprays and TASERs were applied simultaneously. In 2007, the CRT Less Lethal guys published an article on Lawofficer Magazine magazine.

Our test piqued the interest of Mythbusters (episode 146), then CSI (season 8, episode 15), which each featured our experiment in an episode.

During the COVID-19 pandemic, fire associated with a TASER application appeared in the news again with reports of the ignition of a man covered with hand sanitizer. Always remember that a spark from any Conducted Electrical Weapon-CEW (TASER) will instantly ignite flammable substances under the right conditions, causing injury or death.

NFDD- Bangs and Balls

Check out our April 2020 overview of these Noise Flash Distraction Devices (NFDD): flash bangs and blast balls, on YouTube.

Our testing of these devices included the evaluation of flammability potential when used in a tactical environment with CS (tear gas). This testing was featured on Washington’s Most Wanted in 2015.

Also see our article on this topic in the Tactical Edge magazine.

The Axon Taser 7

Our firm has extensive experience analyzing evidence and data related to TASER incidents (see our article). We strive to stay up to date with emerging technology and Leroy and Tom with Seattle PD were kind enough to allow us to test fire the new TASER 7 that they are testing and evaluating.Taser 7 unit and cartridges There are significant differences from other Axon-TASER models, including new cartridges and probes. Taser 7 expertThe T7 cartridges are available in 3.5 and 12 degree configurations to provide user options for range/probe spread.Taser 7 Cartridge  Taser 7

The probes now contain the wire which unspools as they travel down range. The probe head will detach at tangential impacts. Forensically, the probes can analyzed where the wire is crimped to the probe head!Taser 7 probe forensics

Fun with Edgertronic

Due to the wonderful generosity of #Edgertronic,  we borrowed one of their premier high speed video cameras, the SC2+, for an extended time. We were able to do some fantastic experiments and demonstrations related to firearm cycle of fire, bullet impacts, and less lethal weapons. WDF showcased that work at the NTOA conference (National Tactical Officer’s Assocaition) in Orlando,  August 2019. Our seminar, “A Holistic Approach of Police Weapons” was presented to an international audience which received great reviews.

Law Enforcement Technology-Cover

In the August 2018 issue of Law Enforcement Technology, we grabbed the cover with an article on Less Lethal Weapon Integration for police and corrections. The piece discusses selection, implementation and post event considerations that can deescalate volatile situations and reduce liability. We hope it can serve as an initial guide for departments looking to start or improve their less lethal program. The fantastic photos were provided by Jessamy Lennon Photography. Thanks Jess!
