FYI: Someone who knows mentioned, after the illegal was found innocent of shooting the girl on SF pier 14

that SF (which is also its own county) only prosecutes cases in SF if they want an innocent verdict (and of course they don't introduce evidence & witnesses). They transfer cases South to San Mateo county (South of the SF city/ SF county line) if they want a guilty verdict.
Hope there are as few as possible cases tried in SF. A problem with The Storm (if/when it hits) is that if the courts (9th circuit) are flooded, SF will get 'its fair share' of cases (?), which would be very bad if any SF personnel are needed. I'm not really sure about the legal/court details, so I hope this detail is being planned for (or doesn't actually matter since federal/military courts will be used?).
