The two people @nbc hired to consult on the 'Law & Order True Crime Menendez' series were myself and lead defense therapy expert Dr. Bill Vicary. 
My book "The Menendez Murders" was about to be published when the series aired and provided the primary source material for the eight episode limited series.  
Special thanks go to showrunner and creator Rene Balcer and the amazing cast led by Edie Falco, Miles Gaston Villanueva, Gus Halper, Heather Graham, Josh Charles and my prep school friend Harry Hamlin. 95% of the information in the scripted series was factually accurate - unlike the 'Monsters/Menendez' train wreck that came out on @Netflix last fall.
