Marshal Arnwine, Jr.

Advocate, Criminal Justice Program

Marshal Arnwine, Jr. is an Advocate for the Criminal Justice Program at the ACLU of Northern California. In this capacity, he helps lead and organize efforts to reform police policies for 48 Northern California counties. These efforts include implementing AB 392 (police use of force), AB 953 (racial and identity profiling), and SB 1421 (access to police officers’ records relating to police conduct).

Prior to joining the ACLU, Marshal was a law clerk for the San Francisco Public Defender’s Office. In that position Marshal worked in the felony trial unit on homicide cases, with allegations of special circumstances. He transcribed witness statements, analyzed interviews with investigators, communicated trial strategies with clients, and created video collages of pertinent evidence for trial preparation.

While in law school, Marshal worked for the ACLU of Northern California as a criminal justice legal intern. In this role he was a researcher for the “Hey, Meet your District Attorney” campaign report. This report statistically analyzed how elected district attorneys in California misused their influence instead of being stewards of change. Additionally, the report showed how district attorneys took discrepant positions compared to the majority of their constituents on four ballot measures passed since 2012.

Marshal has also worked as a law clerk at the Alameda County Public Defender’s Office where he assisted felony attorneys with felony arraignment interviews. Additionally, Marshal was a law clerk for the Santa Clara Public Defender’s Office, where he argued bail motions, plea negotiations, and motions to suppress evidence.

Marshal is a graduate of the University of San Francisco School of Law, where he received his juris doctorate. He graduated from the University of California-Santa Cruz where he received his bachelor’s in sociology and minor in legal studies. He also played four years on the U.C. Santa Cruz basketball team.

Marshal’s law review article, “Trauma and Learning: Creating Educational Access for Inner City Communities,” was published in Spring 2019 in the University of San Francisco Law Review.

In law school, Marshal served as a research assistant for the Immigration Law Policy Clinic. He was also honored with the CALI award in Legal Ethics for receiving the highest grade in class, and the 2018 Dorraine Zief Law Library award for service to the law school library.

In his spare time, Marshal teaches Sunday school and performs community outreach at Shekinah Christian Fellowship in San Francisco. He also enjoys playing basketball, volleyball, reading, writing, and spending time with his wife.
