In July 2010, Quan along with fellow City Council member and mayoral candidate Rebecca Kaplan were investigated by Oakland police for their actions during a protest following the manslaughter verdict of former BART Police officer Johannes Mehserle. Police claimed Quan and Kaplan joined a "human chain" which prevented officers from clearing a street, while the two countered they were acting as "peacekeepers".<9> No charges were filed against the Councilwomen. Quan was the victim of a street robbery in September of the same year, in her Fruitvale Avenue neighborhood. Quan attributed the crime to lack of employment opportunities in Oakland.<10>
