The union representing San Francisco sheriff’s deputies filed a formal complaint against Sheriff Ross Mirkarimi, linking the Pier 14 killing of Kathryn Steinle to a March order that barred them from communicating with federal immigration agents, according to documents obtained by The Chronicle.
The murder arrest of a man whom deputies had freed from jail despite a felony record and a history of deportations showed that Mirkarimi’s policy “recklessly compromises the safety of sworn personnel, citizens, and those who merely come to visit the San Francisco area,” the deputies wrote in the grievance.
The San Francisco Deputy Sheriffs’ Association called for Mirkarimi to correct his “flawed philosophy” and rescind the March 13 memo prohibiting his staff from giving immigration agents information about detainees — including their citizenship status, their booking and arrest documents, and their release dates.
