Sex Offenders in The American Society.
A sex offender is a person who has committed the crime of employing physical strength or influence so as to obligate others to engage in sexual intercourse or any sexual activity (that includes oral sex, anal sex, masturbation, genital fondling or any sexual content that is not consensual between those involved). As the figure of the sex offender turns out to be usual to some degree, it's increasingly more difficult to fight this problem and prevent our peers and relatives (particularly children) from being exposed to such offender. More alarming is to see those figures that in the majority of cases come to show the sex offender as the victim's acquaintance or even close related.
As the sex offender represents a particular danger even after being released from the law enforcement institution he was being committed to, some countries have established a public sex offender registration. In the USA, the public sex offender registration is a list available either on the internet or local police offices with the names of each and every person in the state classified as sex offender, no matter whether still in jail or released. When a name is included on the sex offender registration, depending on the seriousness of the crime, he stays registered for life and the person's "profile" is required to be updated at least once a year. The person is also obligated to report to the authorities due to any address or job changes. Every state is required to have its own registration, following a law called the Megan's Law, passed in 1996.
This extreme measure that it's being followed by other places in the world, does not aim to expose nor discriminate the person classified as a sex offender, but to encourage people to be aware of the danger this kind of offender represents.
