The city of Oakland, California has hired Bill Bratton, former police chief in LA and NY, as a consultant.  Naturally, the usual "activists" are up in arms.  Matthai Kuruvila and Justin Berton report for the SF Chron:

Famed lawman William Bratton was pilloried by hundreds of Oakland activists who fear he will bring "stop-and-frisk" tactics to the city.

But they're already here.

In fact, the practice is widely used by police across the country and hardly new: The U.S. Supreme Court affirmed its legality nearly a half century ago.

That case, BTW is Terry v. Ohio, an opinion by CJ Earl Warren.
