Missouri’s on-again off-again Halloween restrictions on sex offenders is back on again.

The Missouri legislature passed a law affecting registered sex offenders on Halloween.  Missouri sex offenders must:

• stay in their homes from 5:00 until 10:30 pm,
• turn off all outside lighting, and
• post signs saying, “No candy or treats at this residence.”

The law applies retroactively to sex offenders who registered prior to its passage.   A federal court issued an injunction preventing the law from applying retroactively.  Yesterday, though, a federal appellate court overruled the injunction, allowing the law to protect trick-or-treaters tonight.
