Even though Oakland is the county seat of Alameda County (murders, accidents on I-880, I-980, I-580, and SR24), I doubt these were "Covid" deaths from murders and vehicle crashes (which I know are non-zero in the US). I think these are people who died of other diseases and happened to have tested positive for SARS-CoV-2.
I don't doubt there is roughly similar fauxny "Covid Death" in most/every county in CA (%, not raw numbers), and every state in the US. And even if that vetting were done properly, there would still be an even larger %, IMO, of people whose deaths were due to Covid pushing them over the edge they were already on.
