I wonder what those officers were thinking, arresting a reporter on live camera.
At this point, from some of my friends in the city, it sounds like there just isn't much oversight at all---they've now been caught on video taking guns from people with valid licenses and now arresting the press. I don't think that we can effectively apply logic when the police system seems so disorganized.
I can't say anything about the situation with the Minneapolis PD, but it seems like it has a major training problem, there was also the case a couple of years ago of the cop that shot and killed a (white) woman in her PJs who was reporting a possible crime out of the window of their patrol vehicle.
