A black Oakland firefighter said he was the victim of racial profiling when a white city police officer kept his hand on his gun while temporarily detaining him and his two sons at a fire station, mistakenly believing he might be a burglar. The Aug. 15 incident traumatized his sons, said fire Engineer Keith Jones, 43, of Oakland, who filed a formal complaint with police internal affairs and the Citizens' Police Review Board. [...] Oakland police officials said the officer's response was "within policy," and they released a video from the officer's city-issued chest camera that appeared to contradict some of Jones' account. A police service technician arrived first, found the door open, saw two boys inside and asked for support from officers.
