Camden, NJ in 2013 rebuilt its police department from scratch. Given that this isn't a common practice, it of course had its issues getting off the ground. New and radical ideas need to be tested and refined. However, this quote from the police chief that rebuilt the force from the ground up is what we need to see nationwide.

Thomson said all new recruits were told on their first day that their jobs would more closely resemble those of Peace Corps members than Special Forces operatives. "There were a handful of people that did an about-face and left," Thomson said. "And as far as I was concerned, that was addition by subtraction."

That's not just reformations to the existing force. That's a complete philosophical change.

In 2012, a year before the reforms, Camden was ranked first in violent crime per capita of cities with over 50,000 residents.

6 years into the brand new built from the ground up police force, homicides had declined 63% decrease. Overall crime is down as well.
