From SFGate:

A sergeant under San Francisco Sheriff Ross Mirkarimi who oversaw the department’s shooting range was transferred after he questioned whether the sheriff could take a marksmanship test in light of his domestic violence case, The Chronicle has learned.

Mirkarimi then took the test and failed it, preventing him from carrying a gun, department employees said.

Sheriff’s Department officials strongly denied Thursday night that the sergeant had been transferred because he potentially stood in the way of Mirkarimi’s being granted permission to carry a gun. They described his transfer as a budgetary move and said Mirkarimi had nothing to do with it.
