Bob Herbert sometimes behaves like a very clever hunting dog, alternately flushing his prey and waiting quietly. Of late, he’s been hunting a canard – in this case, a riot which seems not to have occurred.  He makes a compelling case that the Kings County District Attorney’s office seems to be persisting in an unjustified prosecution for no reason other than to save face.  See Herbert’s column Cruel and Gratuitous (Times, February 15, 2008) for details.
