In some states the Adam Walsh Act (AWA) effectively expanded the registries as much as 500%. Since its enactment, critics have expressed concerns about the act's scope and breadth. Several sex offenders were prosecuted under its regulations before any state adopted AWA. This has resulted in one life sentence for failure to register, due to the offender being homeless and not being able to maintain a physical address. The Adam Walsh Act requires anyone convicted of a sex crime to register as a sex offender where it will be posted on the internet for all to see.
