That was definitely an interesting event, copy catted from a similar response in Wayne County which I wasn't involved with, and it showcased the importance of having proven reliable recording gear and many extra units. At least half a dozen recorders failed, including mine. This is part of why I have come to see running go pro's and streaming smart phones as a basic minimum for any time there is a remotely elevated risk of police contact, and the combination has served us well for subsequent situations that were much more dangerous than that was.
A particularly funny thing was a few years ago I met up with a retired cop from that agency who was actually there when called to the commons for backup, because as it turned out he is a friend of my extended by marriage family. I took great satisfaction in informing him that our response was specifically my idea and largely me who coordinated it, which clearly irritated the **** out of him, but he didn't want to make a scene in front of everyone at the reunion.
For what it's worth too, Warren still all these years later does not respect the rights of open carriers. Evil Creamsicle and myself, along with a few other usual suspects were hassled by them last year when we OC'd there for literally only a few minutes after a DPD protest. The only other agencies I've ever encountered that are more consistently brazenly criminal are some of the down river ones.
