A sign taped to the entrance of police headquarters says it all: “Closed weekends and holidays.” Every weekday, the doors are locked at dusk.

It’s not that the cops here are scared; it’s just that they’re outmanned, outgunned and flat broke.

Flint is the birthplace of General Motors and the home of the U.A.W.’s first big strike. In case you didn’t know this, the words “Vehicle City” are spelled out on the archway spanning the Flint River.

But the name is a lie. Flint isn’t Vehicle City anymore. The Buick City complex is gone. The spark-plug plant is gone. Fisher Body is gone.

What Flint is now is one of America’s murder capitals. Last year in Flint, population 102,000, there were 66 documented murders. The murder rate here is worse than those in Newark and St. Louis and New Orleans. It’s even worse than Baghdad’s.
