And don't forget the orders given to NYPD forces in 1991 by Mayor David Dinkins' administration during the first 36 hours of the Crown Heights riots/pogrom in 1991:

Those were the orders that my cop friends received, on the line while wearing riot gear, for the first day-and-a-half of the "rage". Not until Mayor Dinkins was being excoriated in the media were the police allowed to put down the riot.
Alea iacta est.
