The wrongful intrusion into a person's private activities by other individuals or by the government. Tort law protects one's private affairs with which the public has no concern against unwarranted exploitation or publicity that causes mental suffering or humiliation to the average person. The right to be left alone is not always superior to the rights of the public and it may or may not exist or may exist to a lesser degree with regard to the life of a public figure, such as a politician or other person in whom the public has a rightful interest.. The right to personal privacy is encompassed as an aspect of liberty protected against government interference by the Constitution's dueprocess clause. Some of the personal decisions protected from unwarrantedgovernment interference include decisions relating to marriage, procreation, contraception, family relationships, child rearing, and education.
-Dharun Ravi won't be deported back to India for spying on his gay roommate with a webcam at Rutgers University two years ago, federal authorities say. The 20-year-old former student was convicted on 15 counts, including invasion of privacy and bias intimidation, for watching Tyler Clementi kiss another man. Clementi killed himself by jumping off the George Washington Bridge a few days later. Ravi was sentenced to 30 days, but his lack of criminal record apparently saved him from deportation; in fact, he's getting out tomorrow after just 20 days for good behavior.
