Minneapolis hired Brian O'Hara as police chief partly on the strength of his reform credentials, the idea being that a city which had watched an officer kneel on a man's neck for nine minutes might benefit from leadership that took accountability seriously. An independent report has since found that O'Hara probably interfered with an investigation into alleged sexual misconduct within his own department. He has resigned. The mayor described this as a 'breach of trust,' which is one way to characterise a police chief obstructing a misconduct investigation, though 'staggeringly on-brand' is another. Minneapolis has now burned through police chiefs at a rate that would embarrass a mid-table football club. The city remains under a federal consent decree requiring it to reform its police department. The person responsible for implementing those reforms has left under circumstances that would themselves require reform. Officials have expressed confidence that the process will move forward. They did not specify toward what.
