It would forever be a stain on the Detroit, and would only cement people's unfavorable opinions of the city. Also (and probably more important at the moment), it would probably destroy any hope that Snyder has of being re-elected. He has an uphill battle as it is following 'Right to Work', and I would guess that he wasn't too happy about the announcement. There's no way that he doesn't see the political danger of it.
Snyder was the first Republican that got me thinking I could potentially vote for one after I swore never to again after the Bush years and the utter insanity of their collective behavior during Obama's first term. Then he pulled that right to work shit. I said it before, fool me once shame on you, fool me twice shame on me. It's not complicated even slightly. If DIA is raided it is Snyder who did it, quite literally. Orr is appointed and serves at his whim and fiat. All Snyder has to do is say "Hands off or you're out" and hand pick a replacement who understands this. If it happens, it happens with his consent and approval.

me too, but Virg Bernero made it a lot easier of a thought.
