I'll back Shaw up on this. I'm about 45 min. from 'ol D, and let me tell you-he's not exaggerating. You don't need to worry about the cops-they won't come(though if they did for some strange reason, your odds of survival probably go down), and neither will an ambulance....few of them even run.
On a somewhat different note, I watch Detroit news from time to time, and there is a group known as the Detroit 300-who appear to be something akin to Guardian Angels on steroids...without the pretense of not being vigilantes. I remember thinking 'good for them', and also that since that city is a virtual kleptocracy anyway, the whole place would be better off if the police and the entire government were disbanded. I tend to think that about everywhere, but in the case of Detroit I'm not sure it's a radical notion.
That said I DID see quite a few RP signs and so forth in the sticks-particularly Lenawee county. Nice to see, but honestly, this mess is not going to be fixed at the ballot box. I've lived in this area all my life-NW Ohio and SE MI-and I've gotten to know several militia folks as well as an ex-panther organizer, it's frankly amazing to me how much they have in common, but they will never have a common political goal. As others said, RP may have gotten the most of the small fraction of GOP voters in Detroit, but he certainly has no real support in that city.
