Illinois Case Puts Spotlight On Ballistics Analysis Some Say Is Unreliable

On Wednesday, an Illinois appellate court is scheduled to hear the case of a man who says shoddy analysis of a gun led to his wrongful incarceration for more than 20 years. The case could set a precedent for hundreds of other inmates.

It may also force the Illinois State Police to re-examine analysis it's used for decades to help put people behind bars. Max Green (@MaxRaphaelGreen) from WBEZ reports.
