For this week’s MuckReads podcast, ProPublica’s Justin Elliott spoke to the Center for Investigative Reporting’s G.W. Schulz about his reporting on the militarization of local police forces in the U.S. Andrew Becker and Schulz have been the chief reporters on the series, “America’s War Within,” which has shown how federal grants have led local law enforcement agencies to stockpile high-tech combat gear without much oversight.

Elliott wanted to go behind the scenes to find out how the project got started, how they obtained and analyzed the data, their findings and ultimately, who should be held accountable for how the money is spent.
