It's one way to get a lower crime rate

It's an incredible sight: In a city riddled with crime, entire floors of the Wayne County Jail in downtown Detroit are empty.

The seventh floor of the Baird Detention Facility, normally home to 128 newly arrested prisoners, is vacant. So are the ninth floor and half of the 12th floor. Another 128 beds at the Dickerson Detention Facility in Hamtramck are also closed. That adds up to more than 400 empty beds in Wayne County jails that, up to about a year ago, were filled with roughly 2,500 prisoners.

The main explanation is simple, according to the county's top two law enforcement officials: Detroit police are making fewer arrests, a dereliction so obvious it has led some Detroiters to conclude there's no point in even calling the cops.

If you want to get away with Murder, Detroit sounds like a good place:

Even serious crimes aren't getting solved. Arrests are made in only 37% of Detroit homicides, compared to more than 60% nationwide. Officers have too little time to investigate, and they work with a community that often does not trust them. Detroit's shuttered police crime lab has raised more troubling questions about homicide investigations.
