Clementi Said Rutgers Roommate "Spied on Me" With Webcam Pool photo by John O'Boyle Raahi Grover, a resident assistant at Rutgers University, testified at Dharun Ravi's trial on hate-crime charges on Wednesday. NEW BRUNSWICK, N.J. - After discovering that his roommate had set up a webcam in their room and watched him kissing a man, Tyler Clementi sent an e-mail to the resident assistant in the dormitory that said, "I feel my privacy has been violated, and I am extremely uncomfortable sharing a room with someone who would act in this wildly inappropriate manner." The next day, Mr. Clementi, an 18-year-old Rutgers student, jumped to his death from the George Washington Bridge. The resident assistant, Raahi Grover, testified in Middlesex County Court here on Wednesday that when he went to Mr. Clementi's roommate, Dharun Ravi, after the suicide, he tried to explain himself. "I told him, "It's not me who needs to be explained to," " Mr. Grover said. Mr. Ravi, now 20, is facing up to 10 years in prison on charges of invasion of privacy, bias intimidation and hindering apprehension. Prosecutors said that shortly after the roommates arrived at Rutgers in September 2010, Mr. Ravi trained the webcam on Mr. Clementi and a date whom Mr. Clementi had invited to his room, and then encouraged others to watch in what the prosecutors said amounted to a campaign of harassment because Mr. Clementi was gay. Mr. Clementi's suicide set off a national debate about bullying and the difficulties facing gay teenagers. Mr. Ravi's lawyers argue that while his behavior may have been juvenile, it was not criminal. The testimony on Wednesday gave a clearer picture of the demeanor of Mr. Clementi and Mr. Ravi in the days between when Mr. Ravi turned the camera on for the first time and Mr. Clementi's suicide on Sept. Another Rutgers student, Lokesh Ojha, testified that Mr. Ravi pulled him away from a game of foosball in a dormitory lounge on the university's Piscataway campus on Sept. 21 and told him that his webcam had captured Mr. Clementi kissing a man. "He just seemed shocked," Mr. Ojha said. The two then went to Mr. Ojha's room, he said, where Mr. Ravi, knowing that Mr. Clementi had invited his date over again that night, set up the iChat function on Mr. Ojha's laptop to test that the webcam was directed at Mr. Clementi's bed. "He wanted to see that the angle was O.K.," Mr. Ojha said. Mr. Ojha said that Mr. Ravi encouraged him to send text messages to other friends to alert them to watch his Twitter feed, where he told them to turn on their computers to watch the webcam feed. Mr. Clementi had seen the Twitter message about the first encounter and disabled the webcam that night. Afterward, Mr. Grover testified, Mr. Clementi filled out a form online asking to change rooms, giving the reason, "Roommate spied on me with webcam." When Mr. Clementi went to Mr. Grover's room on Sept. 21, Mr. Grover testified, "I could tell by the tone of his voice he seemed a little uncomfortable." Mr. Grover offered him a spare bed for the night, but Mr. Clementi declined. Mr. Grover sent a report to his superiors saying that Mr. Clementi wanted a new roommate "A.S.A.P." and wanted some kind of punishment for Mr. Ravi.
