Distinguishing and disagreeing with Henriksen v. City of Rialto (1993) 20 Cal.App.4th 1612, this decision holds that the City is vicariously liable under respondeat superior for the negligence of one of its police officers in fail to secure a Police Department-approved, secondary firearm upon returning home from work.  The policeman left the gun, unlocked, in his car when he returned home.  It was stolen and used to kill plaintiff’s son.  Given the key role that guns play in a policeman’s line of work, the negligent handling of the weapon was not so unusual or startling that it would seem unfair to include the loss resulting from it among other costs of the employer’s business.
