It's only possible in jurisdictions where DAs and/or Mayors can get elected without an endorsement from law-enforcement, and look at SF for an example of what police do when one slips through the cracks.
By far, most US government is ruled by law enforcement, not the other way around, and this isn't even touching the nationwide police rebellion we've been enduring.
