Ed Maguire is a professor of criminology and criminal justice at Arizona State University, where he also serves as director of the Public Safety Innovation Lab. We chat about the challenges involved in policing protests and demonstrations, and balancing an appropriate response in highly dynamic situations. Maguire shares his knowledge and experiences working with police in the US, the United Kingdom, and Sweden, and we discuss demonstrations including the Occupy movement, Black Lives Matter, and the January 6th Capitol riot.
