Freddie Gray's death from injuries sustained while in police custody in April 2015 fanned the smoldering anger and frustration with police practices in Baltimore into a conflagration of protesting, rioting, and looting.For more than 12 months, WYPR's Mary Rose Madden explored those practices and the culture of policing in Baltimore. She looked at how the relationship between officers and citizens reached that tipping point and reported on racial and class tensions.Once the unrest was over and the cameras were gone, Madden began reporting on the real story behind the headlines in a series called "On the Watch".This special series is supported by grants from the Bendit Family Foundation, Sig and Barbara Shapiro, The Zanvyl and Isabelle Krieger Fund, and Open Society Institute-Baltimore.
