SAN DIEGO — Implementation of a voter-approved police oversight commission in San Diego moved forward Monday with a structure now in place to hire leadership and staff. During a special meeting, the City Council also approved a set of procedures to allow interim commissioners to continue to review police cases while the Commission on Police Practices is set up. “It allows for civilian oversight of law enforcement to continue uninterrupted in the interim,” said interim commissioner Doug Case, who has led an ad hoc committee to help create the new commission. The council also appointed an interim executive director: Sharmaine Moseley, who served as executive director of the Community Review Board on Police Practices.
