Decades of research in management has shown that money is not the sole, or even major, driver of workplace motivation. Workers of all type, including cops, are motivated to put in hard work when they feel like their efforts are recognized and contribute to making a tangible difference.
Generally that's the exact opposite that police in SF have faced over the past few years. Rather than being recognized and respected, they've been repeatedly told, by their own superiors, that they're abusive, reckless and part of a system of oppression. Rather than making a difference, they're participants in a Kafka-esque circus where the criminals they arrest in the morning are released and committing crimes by the afternoon.
I agree that criminal justice reform is important. But there's no politically viable route to that end if it means a mass decline in public safety. And there's no way to ensure public safety, unless police officers feel valued, empowered, motivated and proud to show up for work. You can't just repeatedly demonize and bureaucratize the police, and not expect their performance to degrade because you throw money at them.
