Joe Porter, a black firearms instructor and Cincinnati host of this event, used to be a Facebook friend of mine - until he unfriended me without explanation.
I suspect it had to do with my response to one of his posts which included the suggestion that one place one's ID on one's dashboard during a traffic stop. I posted that I felt that doing so could very well be against a cop's training about reaching into a car, and might also be a Fourth Amendment violation. He deleted it - twice, I believe. The first time, I thought maybe I hadn't posted it properly. The second time, my post was removed and he'd unfriended me.
In general, and over time, I found him to be an individual with a chip on his shoulder.
btw, a video of the Castile encounter was recently released:
