I'm not calling this an "update," because there is no new news about actual happenings. The police haven't returned the cameras yet.
But a couple of pieces of information: First, Acts 17 blog confirms my claim below that they did indeed choose not to press charges last year. The further detail is that this was in exchange for an agreement from the Dearborn police that the particular three Arab festival security men against whom those charges might have been pressed wouldn't be on security duty anymore at the festival. There are a lot of problems with this. For one thing, how could the police actually guarantee that when the security personnel were not themselves a police entity but rather were evidently hired by the festival? And indeed, the promise turned out to be hollow, as one of those men was back this year. Second and more strikingly, the missionaries must have known (from the fact that they were driven out by an entire crowd last year) that the problem is not just with three particular individuals, so why should such an assurance be relevant at all? I don't want to be too harsh on them, but this explanation just does make it all the clearer that the decision not to press charges last year was a real mistake.
Second, two of this year's Dearborn Four are from New York City, and they both say that seeing the mess the Dearborn police department is in makes them appreciate New York City cops all the more. One retired New York policeman has suggested that the feds should investigate corruption, misconduct, etc., in the Dearborn department. Would that we had a different administration and could have some confidence that the present Justice Department would do justice to such an investigation. But formally, he's doubtless on to something.
