[sudo-discuss] help: anti-DAC resources?

Hey guys, a friend of mine who works for the city of Oakland and is meeting with the ACLU on DAC stuff (to fix this nightnare) has asked me for - a coherent, semi-formal argument against the DAC. - Language against specific aspects of the DAC like the shot spotters, facial recognition, etc. What they will be used for vs what they say they will be used for, etc. What resources do we have on hand that I can forward or write up for them? Thanks! David
