This seems like a definitely loss to the world:
Chief William J. Bratton announced Wednesday that he would leave the Los Angeles Police Department after nearly seven years to lead a private international security firm.
At a City Hall news conference here, Mr. Bratton said he was resigning effective Oct. 31 to become chief executive officer of Altegrity Security Consulting, a new unit of Altegrity, whose headquarters are in New York.
One of the most important things in the world is trying to make public institutions work well, since the less-effective ones don’t just naturally go out of business the way corporations do. And yet unfortunately this isn’t something we know a great deal about. One thing we do know, however, is that first in Boston then in New York City and then in Los Angeles Bratton has put together an impressive record of presiding over police departments that succeed in reducing the incidence of crime both in absolute terms and relative to national trends. We need more people like that in public service.
