On 29 years ago today, May 17, 1996 (April 1, 1996 in the lunar calendar), Megan's Act. In 1994, a 7-year-old American girl, Megan, was kidnapped and raped by a sex offender who lived near her home. On May 17, 1996, President Clinton signed the Megan's Law. Put officially documented sex crime case data online for reading; and such criminals must be filed and filed after they are released. Megan: Girls who changed U.S. laws have no household registration system in the United States. For the general public, if they want to move somewhere, they can just move there and live there without having to register with the government. However, there is one exception. No matter where they move, they have to register at the police station first. Of course, these people who are required to register are different from ordinary people: they are sex offenders who have served their sentences. There are a wide variety of sexual crimes in American law, mainly including rape, statutory rape, sexual assault, attempted rape, child molestation, incest, etc. Laws that require mandatory criminal registration are less than a decade old in the United States. People are accustomed to calling this law the "Megan Law". The name "Megan" will always be associated with a heartbreaking past. Megan was a seven-year-old girl at the time, and her story not only changed the sex crime laws of fifty states in the United States, but also changed relevant federal laws. Hamilton, New Jersey is a peaceful and peaceful town. On July 29, 1994, seven-year-old Megan was playing in front of her house when neighbor Jesse came over and said that there was a puppy at home and she wanted to show Megan. Jessie had just moved here and people around him knew very little about him. Curious Megan followed Jessie to his house. Who knew that this was gone and would never return. It turns out that Jessie is a habitual sexual offender and has been sentenced twice for child molestation. Before moving to Hamilton Town, Jesse had just served his sentence, but local law enforcement agencies had no idea about it. After Jessie abducted Megan to her home, she brutally raped her. After Megan disappeared, her parents were anxious. The police and local people searched day and night, searching every corner of the area, but still found nothing. As time went by, the possibility of Megan surviving became increasingly slim. People gradually gave up search efforts. However, the Little Megan incident shocked the entire state of New Jersey, and people hated loopholes in existing laws. Especially Megan's parents. Resisting the grief of losing their beloved daughter, they launched a campaign in New Jersey to amend existing laws, requiring the government to enact laws that would force offenders to register with law enforcement at their place of residence after they are released from prison and make their records public. 89 days after Megan disappeared, the governor of New Jersey signed the first "Megan Act" in the United States, forcing sex offenders living in New Jersey who had completed their sentences to register with the state police. For criminals who pose little harm to the public, law enforcement agencies will notify schools and community organizations; for criminals who pose greater harm, law enforcement agencies will notify not only schools and community organizations, but also street residents. In addition, the state government will establish a unified database to make the names and addresses of these criminals public, and the public can inquire at any time via the phone and the Internet. New Jersey's "Megan Law" is a comfort to little Megan's parents. After winning the first battle, they continued to conduct speeches and lobbying activities across the country. On May 17, 1996, President Clinton signed the federal "Megan Act", requiring released sex offenders to register with law enforcement agencies in the states where they live and make their information public. However, due to the constitutional restrictions on the power of the federal government, the federal government has no right to force states to implement the federal "Megan Act." However, if the state government fails to meet the requirements of the federal Megan Act, the federal government will stop issuing federal grants to states to fight crime. The development of Megan's Law So far, all fifty states in the United States have their own "Megan's Law", which seems to have formed a net. Sex offenders who have served their sentences can only escape registration and the fate of their information being made public by leaving the United States. However, the provisions of the Megan Law vary from state to state, with some lenient and some strict. In Louisiana, the public can inquire about the relocation of sex offenders at will. Some private companies even provide users with the latest addresses of sex offenders via email at any time to warn users that recently released sex offenders have moved to live there. In Washington State, if a released sex offender moves into a new house, police call neighbors door to door to inform them of the offender's name and address. The strictest state is Oregon, where ex-sentenced sex offenders who move to Oregon must post prominent signs on their windows to warn neighbors of their identity. As the Internet becomes popular, states have put information on sex offenders online. People can check at any time whether there are released sex offenders living in the neighborhood where they live. Of course, this approach cannot completely eliminate sexual crimes, but it can reduce the risk of sexual crimes to a certain extent.
