Today on Boston Public Radio: We aired live audio from Gov. Charlie Baker’s Tuesday press conference. Boston City Councilor Andrea Campbell called in to talk about the reforms she’d like to see Boston make to its policing system. We opened lines to ask: what changes would you like to see when it comes to police reform? Former Mass. Gov. Deval Patrick discussed his experience dealing with racism in Massachusetts as a Black teenager, and talked about his impressions of the recent Black Lives Matter protests. Journalist and author Devin Leonard discussed his book “Neither Snow Nor Rain: A History of the United States Postal Service,” and why he believes government leaders won't let the USPS go under. Playwright and painter Ryan Landry talked about the response of art institutions to the Black Lives Matter movement, and how he think communities should deal with statues of racist historical figures.
