"Defund" is an inflammatory word because it implies punishing police departments by taking away budget and firing officers. Repurpose or refocus might be better terms. I heard a professor from NYC's John Jay College say that police departments increasingly have to deal with homeless people, mentally ill people, addicts and others that society doesn't care about--the prof called it "mission-creep." He said that police would welcome it if those people were shifted to social workers, paramedics and others trained to deal with them--it would let police concentrate on law enforcement and crime prevention.
