We did that ten years ago. We know what's wrong.
You can identify any number of dysfunctions and abuses in policing but most of it comes down to one thing: Money. The police have secured enormous municipal budgets, and instead of becoming a tool of last resort, they are the first responders to nearly every social ill.
Not only have they choked off every other effective method to address community problems, but with these massive budgets at stake, the police also secured enormous political power. As a result, they gained impunity for cruelty and malice. 
Serious minds have spent years understanding the effects of runaway police budgets as well as the many alternatives for supplanting this outmoded and brutal model of community safety. A comprehensive review will reveal nothing new. The police are a gargantuan toxic entity.
And with this bloated monstrosity, we are less equipped to address crime humanely, and the most pernicious and toxic forces in this country have a standing army in every city enforcing the aesthetics and substance of their regressive ideals. This is why we say #DefundThePolice.
