Defunding and abolition probably mean something different from what you are thinking. For most proponents, “defunding the police” does not mean zeroing out budgets for public safety, and police abolition does not mean that police will disappear overnight — or perhaps ever. Defunding the police means shrinking the scope of police responsibilities and shifting most of what government does to keep us safe to entities that are better equipped to meet that need. It means investing more in mental-health care and housing, and expanding the use of community mediation and violence interruption programs.
Police abolition means reducing, with the vision of eventually eliminating, our reliance on policing to secure our public safety. It means recognizing that criminalizing addiction and poverty, making 10 million arrests per year and mass incarceration have not provided the public safety we want and never will. The “abolition” language is important because it reminds us that policing has been the primary vehicle for using violence to perpetuate the unjustified white control over the bodies and lives of black people that has been with us since slavery. That aspect of policing must be literally abolished.
