Riddle us this: if it it's so ludicrous to believe that a mysterious black-clad stranger killed punk rock pioneer and realtor to the stars Linda Stein ("NUTTY 'NINJA' ALIBI" screams the Post) than should we conclude that personal assistant and lead suspect Natavia Lowery has also been breaking into homes on Staten Island? When is it ok to blame a ninja? We need answers! [NYP]
