I don't want to defund the police; I do want them to behave like they are part of the neighborhood and not its enforcers.
EDIT: Slashing funding ≠ defunding. It's a terrible, terrible argument that makes no sense, alienates people who'd otherwise support a more reasonable approach, and perfectly embodies the 'all or nothing' style of modern day performance politics.
The only way this can be achieved is through defunding the police. Take away all of their military arsenal budget, cyber spy budget, money for pensions...
The good that money could do the communities it's currently actively harming is almost unfathomable.
Bureaucracies, if left unmanaged as they are today, will always find ways to increase their own budget or resource. It's as true with police departments as it is with... HR departments, or the Catholic Church, or the gun lobby, or unions, or congress, or Google.
The way to manage unchecked behavior is through structures and leadership that aligns incentives to policy. We do it all the time in plenty of other areas of society.
