No. The same standards apply here in the States. When someone has molested a child they are not allowed under the conditions of their freedom to be around children AT ALL! Period. If they fail to keep to these conditions then they are in breach of the guidelines that allows for their freedom in society. Because there is such a high recidivism for pedo's, the breaching of this guideline was what prompted 'Megans' Law'. Megan's law if you are unawares forces government agencies to notify citizens in local communities if a convicted child molester moves into the neighborhood, this way families can protect their children by being forewarned.
Megan's Law is an informal name for laws in the United States requiring law enforcement authorities to make information available to the public regarding registered sex offenders. Individual states decide what information will be made available and how it should be disseminated. Commonly included information includes the offender's name, picture, address, incarceration date, and nature of crime. The information is often displayed on free public websites, but can be published in newspapers, distributed in pamphlets, or through various other means.

At the Federal level, Megan's Law is known as the Sexual Offender (Jacob Wetterling) Act of 1994, and requires persons convicted of sex crimes against children to notify local law enforcement of any change of address or employment after release from custody (prison or psychiatric facility). The notification requirement may be imposed for a fixed period of time - usually at least ten years - or permanently. Some states may legislate registration for all sex crimes, even if no minors were involved. It is a felony in most jurisdictions to fail to register or fail to update information. Megan's Law provides two major information services to the public: sex offender registration and community notification.

Megan Kanka was a seven year old girl who was molested and killed by a convicted child molester who upon release moved into Megan's neighborhood (she lived next door). He lured her into his house to look at some puppies he didn't have and then had the nerve to join the search team when the family realized she was missing. The question after this case was why the family or rather the community were not allowed to know that there was a convicted child rapist living right next door when they had young children living nearby...hence 'Megan's Law'.
