The pseudoscience spreading to police precincts around Illinois

A phenomenon known as 911 phone call analysis is being used by more and more police departments across the country, including in Illinois. It's a pseudoscience that claims that what someone says, how they sound and how they act during a 911 phone call, can determine if they are calling for help, or if they are trying to cover for a crime they have committed.

The 21st was joined by a ProPublica reporter who dug into the practice and its use in the Decatur case of a woman who allegedly killed her child.
