万圣节之夜，孩子们挨家挨户上演“糖果或恶作剧”的时候，也可能会成为一些潜在的危险人物对孩子们下手的好机会。加州管教与感化部今年就宣布一项法令，要求该州2000多名无固定住所的假释性侵犯在万圣节当晚5点至10点之间到设在各市的假释中心报到，以确保他们不会出去惹麻烦。

About 2,000 paroled California sex offenders² have no permanent home partly because of a state law that bans them from living near schools or parks. This Halloween, however, many will spend the night together under supervision³ from authorities who want to make sure they have no contact with children out trick-or-treating.

It's the first time the California Department of Corrections and Rehabilitation⁴ is targeting offenders who live on the streets, under bridges or in nomadic⁵（流浪的） campsites, though it has enforced a curfew（宵禁） on offenders who have permanent addresses for nearly 20 years under what it calls "Operation Boo." The new emphasis comes in response to the growing number of transient（短暂的） offenders, said department spokesman Luis Patino.

Their ranks have spiked⁷ in the five years since 70 percent of voters approved Jessica's Law.

The law bans offenders from living within 2,000 feet of a school or park. As one result, the number of homeless paroled sex offenders grew from 88 in August 2007, before the department began enforcing the law, to about 2,000 now that it has been fully⁸ implemented⁹.

Three of the state's four parole regions are setting up the "transient sex-offender¹ roundup centers," mostly at parole offices or community centers. They include the regions that cover Los Angeles, San Diego, San Francisco and all of California's coastal¹⁰ counties.

Offenders have been ordered to report to parole centers from 5 p.m. to 10 p.m. Monday, where they will be supervised to make sure they have no contact with children out trick-or-treating. The law also required the state to use electronic monitors to track all paroled sex offenders, so parole officers will know if offenders aren't in the curfew centers on Halloween.

California already orders sex offender parolees who have homes to stay inside and turn off their lights, and parolees are barred from putting up Halloween decorations or offering candy.

Patino said corrections officials need to take extra precautions on Halloween to make sure predators¹¹ don't entice¹² children into their homes. However, he said there has been no spike⁶ in child sexual abuse on Halloween since Operation Boo began nearly two decades ago, in part because molesters（猥亵者） tend to shy away from the increased scrutiny¹³.

State Sen. Sharon Runner, R-Lancaster, who co-authored Jessica's Law, praised corrections officials for taking the extra steps to monitor offenders without permanent homes.

Some counties are going further than the state regulations require.

Riverside County this month approved an ordinance¹⁴ barring all registered sex offenders from decorating their homes, leaving on the lights, answering their doors or passing out candy on Halloween. Violations¹⁵ can bring a $1,000 fine and up to six months in jail. Tulare County passed a similar ordinance last year. The ordinances¹⁶ go beyond the parole requirements by applying to all sex offenders, even if they are no longer on parole.
