From the Marshall Project: PowerPoint Justice
At least 10 times in the last two years, US courts have reversed a criminal conviction because prosecutors violated the rules of fair argument with PowerPoint. In even more cases, an appellate court has taken note of such misconduct while upholding the conviction anyway or while reversing on other grounds (as in the case of Sergey Fedoruk). Legal watchdogs have long asserted that prosecutors have plenty of ways to quietly put their thumb on the scales of justice —such as concealing exculpatory evidence, eliminating jury-pool members based on race, and so on. Now they can add another category: prosecution by PowerPoint. “It’s the classic ‘A picture is worth a thousand words,’” said Eric Broman, a Seattle attorney who focuses on criminal appeals. “Until the courts say where the boundaries are, prosecutors will continue to test the boundaries.”
