This week, two cities acted to ban sex offenders from passing out candy on Halloween.

The ordinances passed unanimously by the Hemet and Temecula city councils mirror a measure passed by the Riverside County supervisors earlier this month.

Registered sex offenders will be prohibited from decorating their houses, turning their outside lights on, or opening the door to trick-or-treaters on Halloween night.

The ban passed by the supervisors applied only to sex offenders living in unincorporated areas of the county.

Supervisor Jeff Stone, the ordinance author, sent out a letter to the six cities in his district — Canyon Lake, Hemet, Menifee, Murrieta, San Jacinto, and Temecula — asking them to pass similar measures.

“This way, we will have uniform protections in place by Halloween 2012 for the entire Third District,” he wrote.

Staff at Stone's Riverside office were unsure whether any cities in addition to Temecula and Hemet had passed or were considering similar bans.

The city of San Jacinto, also in Riverside County, already had restrictions on sex offenders' Halloween activities.

According to the Megan's Law Web database, Hemet has 242 registered sex offenders, and Temecula has 48.
