“Multiple agencies involved” isn’t what accountability should look like. The minimum standard is independent scene control: locals/state (not the shooting agency) hold the perimeter, evidence, weapons, video, witnesses, and chain-of-custody immediately, then parallel lanes (OIG + civil-rights + independent charging/recusal), like the accountability gap Vladeck lays out in Vladeck: Accountability After Minneapolis. 

And if you’re wondering why people don’t trust “we’re investigating,” read Chief Judge Schiltz’s letter in Schiltz letter: a sealed filing, no service, and “respond in hours to a petition you can’t even access” is exactly the kind of process rot that kills confidence, context Vladeck flags in Vladeck: Schiltz & DOJ.
