Who knew what when? How sound is the chain of command at City Hall? Are top de Blasio officials’ decisions clearly communicated to agency commissioners? Was a former commissioner asked to leave her position?

Why hasn’t anyone been held accountable for what the administration has admitted was a major mistake?
