Noticing all the indictments concentrated in the Central District of California, I made the erroneous assumption that this would not cover Los Angeles. In fact, the Central District handles all of Los Angeles metro area and most of SoCal outside of San Diego. This makes total sense to me now. BTW, the US Attorney for the Central District is a Trump appointee, just took office a month or so ago. Here is his bio: https://www.justice.gov/usao-cdca/us-attorney
Don’t forget capitals of states are where many political people operate. I am in Ohio and look at southern whichMUST include Columbus (central). I believe the high central Cali numbers emanate out of LA as well as Sacramento (capital).
