Law & Order: SVU pulled out all the stops for their 200th episode. The show took heavy inspiration from the infamous psychology experiments of Stanley Milgram. It also took a cue from a real-life incident which occurred at a McDonalds wherein a female employee was sexually tormented because a police officer on the phone was instructing others to do so. In the show, Robin Williams portrayed Merritt Rook. He was a highly intelligent, manipulative and vile character, yet garnered the sympathy of those around him and sometimes that of the audience. The argument could be made that Rooks actions within the show were not about sexual abuse, but about questioning authority -- hence the episodes title, Authority. Ultimately, after acting as his own defense during trial, Rook was found innocent of the charges against him in relation to the fast food restaurant incident. After becoming a cult hero for his questioning of authority, Rook kidnapped Det. Olivia Benson. When Det. Elliot Stabler tracked the pair down, he was forced to participate in a modified Milgram experiment with Benson as the victim. After a highly emotional scene, Rook revealed it all to be another hoax. As Merritt stated, Stabler had proven himself a man. Shockingly, Rook escaped the two detectives after being apprehended -- although it is speculated he may have drowned himself. Robin Williams electrified in this role. He brought the audience on a journey of emotions -- letting them feel disgust, sympathy, and pity for Merritt Rook. It was one of the better episodes of a show which had followed the same formulaic pattern since its debut and had begun to grow tired.
