The Prosecuting Attorney’s Office prosecutes all felonies in King County. Their decisions are based on experience but minimal statistics. With increased complexity in crimes and rising need to analyze data from multiple law enforcement agencies, we collaborated with their Firearms Violence department and developed an infrastructure to analyze criminal data. The prosecutors got a better understanding of the trends across key metrics. Now, they can analyze bullet casings to link different incidents, extract an individual’s historical criminal involvement and work with law enforcement agencies to increase referral rate, thereby, improving the sponsor's overall data literacy.
