Illinois Gov. JB Pritzker signed a new bill into law Thursday barring police from lying to underage kids during interrogations. From a report: Commonly used interrogation tactics, such as promising leniency or insinuating that incriminating evidence exists, are banned when questioning suspects younger than 18 under the new law, which goes into effect Jan. 1. According to the Innocence Project, an organization focused on exonerating wrongly convicted people, those types of interrogation methods have been shown to lead to false confessions. They’ve also played a role in about 30% of all wrongful convictions later overturned by DNA. Illinois once was called the “False Confession Capital of the United States,” the organization said, because of a number of high-profile exonerations of people who falsely confessed to crimes they didn’t commit. “In Illinois alone, there have been 100 wrongful convictions predicated on false confessions, including 31 involving people under 18 years of age,” said Lauren Kaeseberg, legal director at the Illinois Innocence Project.
