HOUSTON – ‘Chicago Wednesdays’ are back with three of our favorite NBC shows tonight, Chicago Med, Chicago Fire and Chicago PD. I got to chat with stars from each of the shows, Med’s Marlyne Barrett, Fire’s Alberto Rosende, and PD’s Jason Beghe ahead of tonight’s new episodes. Hear what they had to say about wardrobe, portraying important roles of frontline workers, and how they’ve learned each of their crafts with real-life professionals from each department. Also catch ‘One Chicago’ tonight starting at 7 p.m. right here on KPRC 2.

In this image released by NBC, Jason Beghe portrays Hank Voight, left, in a scene from the crime series "Chicago PD." The divide between crime fiction and real life dates back to the genre's origins, more than 200 years ago. Law enforcement violence and corruption were extreme in the mid-19th century and some police forces were rooted in the patrols that used to chase down runaway slaves. Meanwhile, The police in early crime fiction were depicted as good, courageous, and brilliant, says Otto Penzler, the crime fiction publisher and bookseller. Over the past 50 years, the image of law enforcement has sometimes mirrored debates between liberals and conservatives.
