Robert Olson is up for his second contract renewal after six years as chief of Minneapolis police. Olson is expected to win reappointment, even though he faces opposition by some residents and city leaders. His opponents point to rough handling of protestors at a Minneapolis genetics conference earlier this year as evidence that Olson permits a culture of brutality. Opponents plan to speak out at a city committee hearing today but are not likely to sway enough council votes to oust the chief.
