CHICAGO — The basis of the case towards the previous Minneapolis police officer charged with killing George Floyd is a mountain of video proof, however presenting that to jurors is not as simple as pushing play.

Over and over, prosecutors have proven video from surveillance cameras, bystanders’ cellphones and police physique and sprint cameras, and have requested witnesses to annotate footage or pictures and narrate the motion on display.

Large screens or projectors are fixtures of contemporary courtrooms, alongside software program much like PowerPoint designed for courtroom presentation of movies, pictures and different proof. But the standard of that know-how and attorneys’ use of it varies.


The courtroom getting used for Derek Chauvin ‘s trial is the biggest and just one within the Hennepin County courthouse geared up with the instruments to current and annotate video and different visible proof.

Jurors are capable of see proof on three displays.

A touchscreen monitor is positioned on the witness stand. Prosecutors have been asking witnesses to circle themselves or level out particulars utilizing a stylus.

Hennepin County Judge Peter Cahill has a monitor at his bench, and he is capable of management when a witness’ annotations are seen to the courtroom.

Prosecutors have performed dozens of video clips from bystanders’ cellphones, the cameras Chauvin and different officers wore, and surveillance cameras on the road and contained in the neighborhood retailer the place Floyd was suspected of passing a counterfeit $20 invoice.

The protection has but to start presenting its case however Chauvin’s lawyer, Eric Nelson, has indicated he can even depend on video proof to indicate his shopper just isn’t responsible.

Cahill and the attorneys additionally use a system of headphones and microphones that permits them to talk privately and stay socially distanced, as an alternative of approaching the decide’s bench.


The pandemic has pressured many courts to rapidly embrace know-how, and a few hope these constructive experiences will encourage extra attorneys to make use of tech instruments as they return to courtrooms.

But many attorneys haven’t got the time and sources to arrange a presentation to the extent of element seen within the Chauvin case, stated Jessica Silbey, a professor on the Boston University School of Law.

Michael Moore, the Beadle County State’s Attorney in japanese South Dakota, stated value is the highest deterrent for a lot of attorneys, adopted by discomfort.

Moore stated he ceaselessly makes use of software program to create timelines, show paperwork and different visible proof in instances. He believes it is simpler for jurors to observe his arguments and it saves time at trial in comparison with old-school handouts of pictures or paperwork.

But as a rule, Moore stated, courtrooms are usually not “wired” for legal professionals who embrace such instruments. Moore brings his personal flat display monitor to some trials to make sure jurors have an excellent view.

It’s tough to know what number of courthouses within the U.S. can accommodate such know-how.

Prosecutors made no secret of their technique to maintain jurors’ deal with video proof capturing Chauvin’s actions. During opening arguments, prosecutors performed the total video of the encounter and emphasised that the officer pressed his knee on Floyd’s neck for 9 minutes, 29 seconds.

Lawyers arguing a case involving vital video proof can not assume that everybody views it by means of the identical lens. Silbey stated. They should focus jurors’ consideration by slowing footage down, circling or highlighting an occasion, and narrating what is occurring.

“Lawyers make a mistake if they assume people see what they see and that the video speaks for itself,” Silbey stated.

People perceive and keep in mind info extra simply when it is accompanied by a visible assist, Lederer stated.

“Presenting information visually enables judges and jurors to better understand what’s happening,” he stated. “And from a lawyer’s standpoint, if you have good evidence, you can persuade better.”

Attorneys should stroll a inflexible line, although. One memorable misstep triggered a New Jersey Supreme Court evaluate and led justices to overturn a financial institution theft conviction in January.

The prosecutor improperly used a picture of Jack Nicholson in “The Shining” in a slide displayed throughout her closing argument, the courtroom discovered.

“Visual aids such as PowerPoint presentations must adhere to the same standards as counsels’ spoken words,” the opinion learn.
