Note that an update today was provided that the State Bureau of Criminal Apprehension is unable to do anything meaningful to investigate the incident because the FBI has backtracked on previous indications of cooperation and decided to deny them access to any evidence gathered in the course of the federal investigation (and obviously, federal agents controlled the actual crime scene, are the only ones who even have the identity of the agents involved—though what they revealed about background in attempting to burnish the image of the shooter without identifying them has led to a probable identification of the shooter—and control essentially the bulk of the physical evidence.)
