The irony is that Mayor Running-for-President set out to rid the city of broken-windows policing — the well-tested notion that little crimes left unaddressed beget bigger crimes — and he succeeded. Now the subways stink of urine and it has all come roaring back. When an in-your-face town like New York suddenly realizes that City Hall tolerates minor crime — as a matter of social equity, no less — it gets more of it, fast. Presently, citizens are pouring water on cops. One shudders to think what comes next.
