The study found that sex offenders viewed community notification as more unfair than did members of the general public, and sex offenders viewed the law as less effective than did the general public. There were also significant differences between sex offenders and the public in awareness of the negative consequences of the law. Specifically, sex offenders experienced more vigilantism than was known to the public. The finding suggests that community notification about the identity and location of sex offenders may fuel negative attitudes and behaviors toward sex offenders that make it more difficult for them to reintegrate into society, thus increasing their risk for reoffending. When an offender is isolated or alienated from positive social interactions and bonding, the desire and support for normative behavior is undermined. The authors suggest a more discriminating approach to notification based on empirically derived risk assessment, which will benefit the public by increasing their awareness of the most dangerous offenders while not unnecessarily creating reentry barriers for those sex offenders who are least likely to pose a threat to the public. The study included 125 adult sex offenders who were receiving outpatient treatment in Central Brevard County, FL, and 193 adult members of the nonoffending public in Melbourne, FL. The sex offenders resided throughout Brevard County and were recruited through sex offender outpatient treatment facilities. The Sex Offender and Public Questionnaires used identical questions in collecting information about perceptions of the current community notification law and its ability to prevent further sexual abuse of children. 4 tables, 1 figure, and 38 references
