That was my first thought too, Reedus. And neither of us think it's good optics (at least it wasn't done within the first week).
But he reminded me that the investigation is being done not just in parallel, but with the oversight of the FBI, and the guys in the pic don't represent the investigators of this case, or necessarily, any investigators.
If the evidence wasn't overwhelming, we would see different things happening, from the governor to the DOJ, to these guys.
Just my guess, but I expect we'll see them wait until the heat simmers down, then more emphasis on the DOJ investigation of the department, and that will be given a lot of publicity alongside the evidence that exonerates ODW in the eyes of a critical majority.
There will always be people who cry foul conspiracy. We still have 911 truthers after all. And in this case, we still have people even today publishing things like he was left uncovered for all those hours and that MB never robbed the store.
It's going to take both of these two PR firms to help get the truth out without having not just Ferguson, but other cities burn.
