In New Jersey, the police have an odd enforcement tactic against drunken driving. Cops often list in newspapers the specific areas where there will be DWI checkpoints.
Why? I don’t know. Anyone planning to get boozed up and behind the wheel can simply go a different way and not get caught.
New York does pretty much the same thing in going after Medicaid fraud, according to a well-connected whistleblower who doesn’t want me to reveal his name. Each year, the New York State Office of the Medicaid Inspector General issues a “Work Plan” — a “blueprint,” it’s called — that explains what enforcement actions will be on the agenda.
