It's the reverse. Between The Ferguson Effect and that reality that these cities are bankrupt, these cities can't attract police officers so they find some rabble-rousers to scream "Defund the Police". They found black rabble-rousers especially because a very large percentage of black citizens in want more police and these cities can't hire them.
These politicians are looking right in the eyes of the citizens who want and need the police the most and telling them, "we're cutting police departments for you".
"Your loved one wasn't murdered, beaten, raped, or mugged because we ran this city into the ground. They were murdered, beaten, raped, or mugged because racist police needed to be defunded - that and Orange Man Bad."
On the commie federal level - where local city politics are just one more incentive to consider in the commie insurrection - I'm right.
