Residents of Baltimore are in the process of regaining calm after the city was rocked by violence. 

Protests broke out after the funeral of 25 year old Freddie Gray. Gray died April 19th of spinal cord injuries while in police custody.

In the ensuing protests, Baltimore police said 15 officers were hurt after they were struck by bricks, stones and glass bottles.  

We find out more about the situation in Baltimore with Kenneth Burns. He's a reporter for NPR station WYPR. 

And then for a look at the role police play at moments like these, we talk to Cheryl Dorsey, a retired LAPD sergeant, expert on police culture and author of the book, "The Creation of a Manifesto, Black and Blue." 

We're also joined by Eugene O'Donnell - former NYPD officer and professor of law and police science at John Jay College of Criminal Justice.
