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

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!

Pepperball TCP

A compact version of the old Tiberius, this is a little CO2 driven, magazine fed six shooter that fires the VXR shaped round. It’s a nice, accurate device with a rifled barrel and variable velocity with the same impact qualities as their big brothers.

Drones (UAS) for Forensic Use

In 2013 using a Leica Aibotix UAS (Unmanned Aerial System), we assisted in the scene reconstruction and a photogrammetry fly-through of an 800 yard scene, which was presented at AFTE and Hexagon conferences in 2014.  Since then, advances in technology, reduction of cost, and more defined FAA rules have made it easier for law enforcement and other public safety agencies to utilize these tools for hyper accurate measurements of large crime scenes and accident reconstruction.

In April 2018, Holmans USA provided a demo for us in NM of the latest UAS available for Leica. Wyant is a FAA Part 107 certified UAS pilot, which allows drone use for commercial operations including aerial photography, 3D crime scene mapping and documentation. With WD Forensic’s two aircraft, we are excited to apply the latest technology to our forensic consulting casework and training. Come see our presentation at the September 2018 SIFIR conference.
