Why is Kari Brandenburg covering for APS leadership?

The leadership of the APS promised to turn over to the DA,
credible evidence of criminal misconduct, including felony
criminal misconduct, by some senior APS administrators.

APS' Rigo Chavez now admits that, almost two years later,
APS has not turned a single document over to the DA.

When asked about the evidence that had been surrendered
to her office, instead of admitting that she was yet to receive
even one piece of evidence, Kari Brandenburg implied that
evidence had been turned over when she refused to reveal
anything about the evidence subsequent to requests for
public records.

Had Brandenburg been as candid, forthright, and honest
as the law allows, it would have become obvious more than
a year ago, the APS was still hiding credible evidence of
felony criminal misconduct from law enforcement.

Had Brandenburg been as candid, forthright and honest
as the law allows, we would not now be so close to expiring
statutes of limitations that it looks like APS good ol' boys
are going to slide on accountability for criminal misconduct.

All of which begs at least a few questions;

Must we simply accept allowing members of the privileged
class to collude to hide evidence and protect each other from
the consequences of even felony criminal misconduct?

Is there really nothing that can be done by the powerless
to hold the powerful truly accountable to meaningful
standards of conduct and competence as public servants?

Or will they simply continue to ( let each other) slide on
the consequences of even the most reprehensible misconduct?
