OR:

A sex offender (sexual offender, sex abuser, or sexual abuser) is a person who has committed a sex crime. What constitutes a sex crime differs by culture and legal jurisdiction. The majority of convicted sex offenders have convictions for crimes of a sexual nature; however, some sex offenders have simply violated a law contained in a sexual category. Some of the serious crimes which usually result in a mandatory sex-offender classification are

. In the U.S., registry databases are often open to the public. Sexual offenders are sometimes classified by level. The highest-level offenders generally must register for their entire lives; low-level offenders may only need to register for a period of time.


Recidivism

The level of
recidivism Recidivism (; from ''recidive'' and ''ism'', from Latin ''recidīvus'' "recurring", from ''re-'' "back" and ''cadō'' "I fall") is the act of a person repeating an undesirable behavior after they have experienced negative consequences of th ...

, observed recidivism rates of sex offenders are underestimated of actual reoffending. This is due to reasons such as the frequency with which sex crimes are not reported to police, the disparity between the number of sex offenses reported and those solved by arrest, and the disproportionate attrition of certain sex offenses and sex offenders within the criminal justice system. For example, Grotpeter and Elliot (2002) found that only 2.5 % of sexual assaults and 10 % of serious sexual assaults resulted in an arrest. A 2002 study by the Office of Justice Programs (OJP) following 9,691 male sex offenders released from prisons in 15 US states in 1994 indicated that within the first 3 years following their release, rearrest and reconviction rates for new sex offenses were 5.3 and 3.5 percent, respectively; that is, about 1 in 19 of released sex offenders were arrested within three years for another sex crime. The same study found that during the same 3 years from release, 68 percent of released non-sex offenders were re-arrested for any crime (and 47.8 percent reconvicted), while 43 percent of the released sex offenders were rearrested for any crime (and 24 percent reconvicted). According to the Office of Justice Programs (OJP), in New York state, the recidivism rate for sex offenders has been shown to be lower than any other crime except
murder Murder is the unlawful killing of another human without justification or valid excuse, especially the unlawful killing of another human with malice aforethought. ("The killing of another person without justification or excuse, especially the ...
. Another report from the OJP which studied the recidivism of prisoners released in 1994 in 15 states (accounting for two-thirds of all prisoners released in the United States that year) reached the same conclusion. Of released sex offenders who allegedly committed another sex crime, 40 percent perpetrated the new offense within a year or less from their prison discharge. Within three years of release, 2.5 percent of released rapists were rearrested for another rape, and 1.2 percent of those who had served time for homicide were arrested for a new homicide. Sex offenders were about four times more likely than non-sex offenders to be arrested for another sex crime after their discharge from prison (5.3 percent of sex offenders, versus 1.3 percent of non-sex offenders). In 1991, an estimated 24 percent of those serving time for rape and 19 percent of those serving time for sexual assault had been on probation (or parole) at the time of the offense for which they were in state prison. Approximately 4,300 child molesters were released from prisons in 15 U.S. states in 1994. An estimated 3.3 percent of these 4,300 were rearrested for another sex crime against a child within 3 years of release from prison. Among child molesters released from prison in 1994, 60 percent had been in prison for molesting a child 13 years old or younger. The median age of victims of those imprisoned for sexual assault was less than 13 years old; the median age of rape victims was about 22 years. Child molesters were, on average, five years older than violent offenders who committed their crimes against adults. Nearly 25 percent of child molesters were age 40 or older, but about 10 percent of inmates with adult victims were in that age group. The recidivism rate for chikans and voyeurs is considerably higher than for other sex offenses, according to the Crime White Paper 2015 published by the Ministry of Justice of Japan. The survey reported 85.0% of the molesters and 64.9% of the voyeurs had a prior conviction for a sex offense.


Risk Assessment

Various methods can be used to assess individual sex offenders' recidivism risk. Some risk assessment tools consider factors that have been empirically linked by research to sexual recidivism risk. These factors include biological and demographic markers, criminogenic correlates, behavioral and developmental indicators, and clinical markers that have been shown to be associated with reoffending. However, the quality of the studies that link various factors to sexual recidivism risk vary widely in terms of methodological rigor. For example, some studies link certain factors to sexual recidivism risk through clinical
anecdotal evidence Anecdotal evidence is evidence based only on personal observation, collected in a casual or non-systematic manner. The term is sometimes used in a legal context to describe certain kinds of testimony which are uncorroborated by objective, indepen ...

approaches, including experimental methods. There are at least four classifications of structured sexual recidivism risk assessment tools: empirical actuarial, mechanical, adjusted actuarial, and structured professional judgement. Of these classifications, empirical actuarial tools are the most methodologically rigorous because they contain explicit empirical risk factors, defined in advance, that are combined mechanically using explicitly defined guidelines into a score or risk category, and then linked to a recidivism probability estimate. Structured professional judgement (SPJ) tools are among the least methodologically rigorous risk assessment tools, because these tools specify items to be considered, and ultimately the clinician subjectively integrates the factors to reach assessment conclusions like “low,” “moderate,” or “high” risk. Furthermore, clinicians may also use unstructured sexual recidivism risk assessments, where they do not use any structured guidelines to aid in their risk assessment. Researchers and practitioners consider some factors as "static", in that they do not change with time, such as number of prior sex offenses, victim gender, and deviant sexual arousal, and some other factors as "dynamic", such as an offender's compliance with supervision and treatment. By examining both types of factors, a more complete picture of the offender's risk can emerge, compared with static or dynamic factors used alone. There is no single assessment tool that clinicians must use for assessing sexual recidivism risk, but there are tools that are widely used, such as the Static-99R. The Static-99R is the most popular actuarial scale in the United States. The Static-99R is a 10-item scale for ranking a sex offender’s relative risk of sexual recidivism compared other offenders. This scale is based on demographic and criminal history data, for example, age at release and number of prior sex offenses. Researchers have shown that the Static-99R is valid across a wide range of individuals (in terms of demographics, such as race/ethnicity). However, the Static-99R has only a modest ability to discriminate correctly between sex offenders and non sex offenders. This means that a randomly selected sex offender would be correctly classified as higher risk than a randomly selected non sex offender with "modest" accuracy. In addition, the Static-99R does not account for every factor that makes a sex offender more likely to reoffend. Despite these shortcomings, the Static-99R is arguably the highest quality tool, in terms of methodological rigor, that is widely available to clinicians to assess sex offender risk of recidivism.

is a system in place in a number of jurisdictions designed to allow authorities to keep track of the residence and activity of sex offenders (including those released from prison). In some jurisdictions (especially in the United States), information in the registry is made available to the public via a website or other means. In many jurisdictions, registered sex offenders are subject to additional restrictions (including housing). Those on parole (or probation) may be subject to restrictions not applicable to other parolees or probationers. These include restrictions on being in the presence of minors, living in proximity to a school or daycare center, or owning toys (or other items of interest to minors). Israel's sex offender registry is accessible only to security officials, rather than to the general public. Megan's Law, in the U.S., is designed to sanction sex offenders and reduce their recidivism rate. The law is enacted and enforced on a state-by-state basis. Most states also restrict where convicted sex offenders can live after their release, prohibiting residency within a designated distance of schools and daycare centers (usually ). Guided by the 2007

However, residence stipulations vary from state to state.

and treatment professionals as Atsa. Committing to a residence requires a convicted sex offender to be notified of registration regulations by local law enforcement if convicted after January 1, 2005. The offender must act upon the notification within five business days of receipt. If and when an offender is released from incarceration, they must confirm their registration status within five business days. Registration data includes the offender's sex, height, weight, date of birth, identifying characteristics (if any), statutes violated, fingerprints and a current photograph. An offender's email addresses, chat room IDs and instant-messaging aliases must be surrendered to authorities. In Colorado, an offender must re-register when moving to a new address, changing their legal name, employment, volunteer activity, identifying information used online or enrollment status at a post-secondary educational institution. A web-based registration list may be found on county websites, which identifies adult convicted sex offenders who are sexually-violent predators convicted of felony sexual acts, crimes of violence or failure to register as required. Legally, "any person who is a sexually violent predator and any person who is convicted as an adult...has a duty to register for the remainder of his or her natural life". Exceptions to this include deferred sentencing for the offense or petition of the court for termination of registration. Some sex offenders are deemed too dangerous to society to be released, and are subjected to civil confinement — indefinite continuing incarceration, which is supposed to, but does not always, provide meaningful treatment to the offender.

programs use covert sensitization and/or odor aversion: both are forms of aversion therapy, which have had ethical challenges. Such programs are effective in lowering recidivism by 15–18 percent. The use of aversion therapy remains controversial, and is an ethical issue related to the professional practice of behavior analysis. In 2007, the Texas State Auditor released a report showing that sex offenders who completed the Texas Sex Offender Treatment Program (SOTP) were 61 percent less likely to commit a new crime.
Chemical castration Chemical castration is castration via anaphrodisiac drugs, whether to reduce libido and sexual activity, to treat cancer, or otherwise. Unlike surgical castration, where the gonads are removed through an incision in the body,
is used in some countries and U. S. states to treat male sex offenders. Unlike physical castration, it is reversible by stopping the medication. For male sex offenders with severe or extreme paraphilias, physical castration appears to be effective. It results in a 20-year re-offense rate of less than 2.3 percent (versus 80 percent in the untreated control group), according to a large 1963 study involving a total of 1036 sex offenders by the German researcher A. Langelüddeke. This was much lower than otherwise expected, compared with overall sex offender recidivism rates. Although considered cruel and unusual punishment by many, physical castration does not otherwise affect the lifespan of men (compared with uncastrated men).

It is argued that in the U.S., sex offenders have been selected as the new realization of
