A southern California city bans sex offenders from decorating for Halloween and now the city is facing a lawsuit over the ordinance.

Five California sex offenders and their families are suing the city of Simi Valley claiming that the Halloween restrictions violate their right to free speech.

Under the ban, they are also required to turn off all exterior lighting and post a sign on their doors that reads in at least one-inch-tall letters: "No candy or treats at this residence."

Janice Bellucci, an attorney representing the plaintiffs and head of California Reform Our Sex Offender Laws, an advocacy group that fights for the civil rights of registered sex offenders, said the sign requirement was particularly troubling.

The city attorney for Simi Valley hasn't commented.

What do you think? Public safety measure or violation of civil rights?
