Show notes:


Knott Laboratory LLC is a forensic engineering and animation firm, and has created Digital Media Forensics; a new division to assist law enforcement with in-depth analysis of digital evidence.

 


What Digital Media Forensics can do for law enforcement:

Recreate crime scenes in 3D

Discover facts in a case and eliminate issues

Create transparency

Present the case clearly to a jury.


 

For example, Digital Media Forensics can use video and audio evidence from: 

\\xb7        Body worn cameras 

\\xb7        Surveillance cameras 

\\xb7        Patrol dashboard cameras 

\\xb7        Cell phones 

\\xb7        Video doorbells 

\\xb7        Traffic cameras 

\\xb7        Photographs from the scene 

\\xb7        Drone footage 

 

And merge this evidence with a Point Cloud to find key factors, such as: 

\\xb7        Positions of people, vehicles, and objects 

\\xb7        Second-by-second timeline of events 

\\xb7        Speed, pitch, yaw, roll, and angles of objects 

\\xb7        Locations of evidence 

\\xb7        Points of rest 

 

\\u201cDigital analysis at this level is a new necessity for law enforcement,\\u201d said Stanley Stoll, CEO/Principal Engineer at Knott Laboratory. \\u201cWe see cases scrutinized in the media. Every detail in our work is scientifically accurate, providing that needed transparency, while clearly presenting the facts of the case.\\u201d 

 

In addition to video analysis, Knott Laboratory\\u2019s Digital Media Forensics experts can use Motion Capture, Real-Time Simulation, Interactive Visualizations, and Virtual Reality to create custom case presentations. 

 


Video Evidence is objective, or is it?

The viewer is not objective

Much of the important evidence is in the data you don\\u2019t see

How do you help remove the \\u201cperspective\\u201d of the viewer?


How can agencies respond to high visibility incidents better? 

How long does it take so get at least a baseline understanding of what happened once you have all the video?

How do agencies begin working with Knott Labs?

Is this the new norm? Will we see OIS go through a review process using this tech without exception at some point in the future?
