“…The form that notification takes varies from state to state (e.g. door-knocking, community meetings, posters, flyers, social media; see Harris et al, 2015), but federal legislation mandates that all states must maintain a publicly accessible online sex offender register (see Thomas, 2011). The information that is published generally includes the offender's name, date of birth, gender, address, past convictions, a physical description and photograph, and may also include his or her driver's licence number, a description of his or her motor vehicle including licence plate number, his or her place of employment, his or her victim's gender and age, and risk rating (see Ackerman et al, 2011 for a descriptive analysis of the content of statebased online public sex offender registries).…”
