Al Lum

Sergeant Albert Lum of the San Francisco Police Department's domestic violence unit explained that all officers receive mandatory training in domestic violence investigation and are trained to not express any overt bias.The officers who investigate domestic violence cases may be part of special police units.The number of cases can be staggeringly high.San Francisco, alone, has approximately 250 felony arrests per month for domestic violence cases.

Al Lum, investigator with SFPD's domestic violence unit, referred the case to the Adult Probation Department, not the district attorney! Why? Because, Lum told the San Francisco Chronicle, Joyce Tempongko had been drinking the night of the incident, had not been hospitalized and had not called police to check on the progress of the case.

"It's up to her to call or come in for a follow-up," Lum said.
