I lived in Oakland briefly. I can't speak to Oakland crime broadly, but I will say one of the big drivers of crime is gangs. In Baltimore city where I grew up, the crime is drug related so shootings are targeted and don't have collateral damage. In Oakland, the gang-related shootings tend to be spray-and-pray with innocent bystanders getting caught in the middle. I moved out of Oakland after one such shooting happened < 100ft from my nice $2k a month apartment.
