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:

· Body worn cameras

· Surveillance cameras

· Patrol dashboard cameras

· Cell phones

· Video doorbells

· Traffic cameras

· Photographs from the scene

· Drone footage

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

· Positions of people, vehicles, and objects

· Second-by-second timeline of events

· Speed, pitch, yaw, roll, and angles of objects

· Locations of evidence

· Points of rest

“Digital analysis at this level is a new necessity for law enforcement,” said Stanley Stoll, CEO/Principal Engineer at Knott Laboratory. “We 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.”

In addition to video analysis, Knott Laboratory’s 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’t see

How do you help remove the “perspective” 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?
