I encourage everyone reading this, regardless of where you live, to
   contact [1]California Assemblyman David Chiu.  Chiu is a the California
   state legislator for the district including San Francisco.  He is a
   mainstream elitist/financialist Democrat, but historically he has been
   close to the Silicon Valley tech community.
   When you call Chiu's office, explain the Murdock case if the staffer
   you speak with is not familiar.  Politely mention that the SFPD is
   widely known to be corrupt.    Then ask that the Assemblyman work to
   have the incident investigated by an independent investigator from
   outside the San Francisco Police Department.  A state assemblymember
   does not have direct legal authority to appoint an investigator - but
   for sure, if an elected legislator speaks out, many people will listen.

   Assemblyman Chiu's office phone number is (916) 319-2017.  You can also
   contact him electronically thru [2]his official website.
   Some members of this list may criticize this suggestion as naively
   optimistic.  Maybe it is; but I guess I haven't completely given up all
   hope for our "democratic" political institutions.  Anarchists will call
   that foolish; the rest will, I hope, call Assemblyman Chiu's office.

     "The police are uneducated, evil, and sadistic. Do not trust them. …
     The rest of my life is to fight against the police. … they are NOT
     friends, so don’t ever ever believe otherwise.”
     Anyhow...
     Reddit seems to think it's some combination of pressure, health /
     medication,
     philosophy, etc yielding yet another unraveling.
     Reiser, Schwartz, Murdock... others...
     Learning from such things, were it to be, is a lucky priviledge and
     moment of insight.
