Protesters in Minneapolis took to the streets again this weekend to express their concern about policy brutality, joining a wave of demonstrations across the country.

The protests follow separate decisions by grand juries in Ferguson and New York not to indict white police officers in the deaths of unarmed black men.

These high-profile incidents, along with the shooting last month of a 12-year-old African-American boy by police in Cleveland, have put long-running debates about race and policing back in the spotlight. Police departments nationwide are facing heightened scrutiny of their work.

Maplewood Police Chief Paul Schnell and Roseville Police Chief Rick Mathwig join The Daily Circuit to talk about how police are trained to handle confrontations, the relationship between police and communities of color, and how recent news is affecting their work.
