Kenneth Thompson, Brooklyn’s first African-American district  attorney, indicted Liang. At the officer’s arraignment, Thompson said he didn’t  believe Liang intended to kill Gurley. “What the evidence showed is that this  police officer put his finger on the trigger and fired that gun into a darkened  stairwell when there was no threat.” 
      Complicating the racial outlook, the judge presiding over the  Liang case will be Denny Chun, a Korean-American. He’ll be under tremendous  pressure from all sides. 
      However the trial plays  out, Liang is a goner at the NYPD. Not realizing he’d shot anyone and afraid  he’d be fired for improperly firing his weapon, neither he nor his partner ran  or radioed for help for four minutes after the shooting. Those four minutes  could doom him — both at his criminal trial and at the NYPD, where as a rookie  he can be fired summarily. 
      
        THE FADE OUT. Over at  Barnes and Noble in Manhasset L.I., former police commissioner Ray Kelly’s  book, “Vigilance” with its modest subtitle: “My Life Serving America and  Protecting Its Empire City” is now on sale for half price. That’s an indication  the book is fading. 
       As is Kelly. His last  month’s broadside, charging the department with deflating shooting statistics  to make the city appear safer than it actually is produced a retort from police  commissioner Bill Bratton to be “a big man” [a dig at Kelly’s sensitivity about  his stature] and to name his sources or  shut his yap. Kelly hasn’t opened it  since. 
       Meanwhile, the 74-year-old  Kelly was seen at the funeral of the state’s former top judge, Judith Kaye,  “walking with a wobble,” as one person put it. “He wasn’t unsteady,” said this  person. “But when you get older, you don’t walk as straight.” 
       Still, don’t count out the  longest serving police commissioner in the city’s history. Gov. Cuomo hasn’t.  In his state-of-the-state address last week, Cuomo stated that he had called on  Kelly “to tell us the best way to defend ourselves and the state’s  counter-terrorism operations.” Kelly recommended moving  the state’s counterterrorism operations to the jurisdiction of the state police  to improve intelligence sharing and reduce response time. 
       The Post’s Bob McManus, as  usual, got it wrong, writing that Cuomo had accepted Kelly’s proposal “to relieve the city of  substantial responsibility for combating terrorism.” 
       Such nonsense caused  consternation within the NYPD’s Public Information office, which has apparently  not yet learned that anything you read in the Post should be confirmed  elsewhere.
