Minnesota?s complex debate about police body-cameras takes a new turn in St. Paul Wednesday. The City Council will hold a public hearing at 5:30 p.m. to consider the draft policy released last week by the St. Paul Police Department governing use of the cameras that are typically clipped to an officer?s uniform. In a discussion that involves competing interests and tradeoffs, there?s lots to digest as the department prepares, beginning next week, to test two camera systems over 60 days in its Western District.
