Check this out - our LA County Board of Supervisors just posted a motion today around marijuana-related conviction expungement. It specifically called out Code for America and their work with the San Francisco DA as an example: http://file.lacounty.gov/SDSInter/bos/supdocs/133510.pdf
I’m hopeful this can lead to change in our County-level governments. 
Anyone else have good examples? I think it would be useful to have a list of these official motions for reference so that when we encounter friendly offices, we can point them to real life examples of what other municipalities have done!
