CONTAINED: Stabbing of 9-year-old Staten Island boy eyed as ‘ISIS audition.’ “An alleged jihadist arrested in June on charges that he plotted to blow up Times Square may also be the fiend who stabbed a 9-year-old Staten Island boy in the neck five months earlier in what some investigators now believe was a botched ISIS audition. But NYPD detectives investigating the Jan. 9 knife attack have been frustrated by the feds, who won’t give them access to terror suspect Fareed Mumuni, said a source familiar with the probe.” Why not, feds?
