What it would do: Increase the penalties for human trafficking, especially the sex trafficking of children, and require training for law enforcement on handling trafficking complaints. Expand the definition of human trafficking and require sex offenders to provide their email addresses and Internet identifiers to law enforcement.
Support: Former Facebook Chief Privacy Officer Chris Kelly is the main proponent behind the initiative, along with the anti-human trafficking nonprofit California Against Slavery. The measure is endorsed by the state's Democratic and Republican parties and numerous law enforcement groups and victims' advocates.
Oppose: Some trafficking victims' advocates are opposed. So are sex workers represented by the Erotic Service Providers Legal, Education and Research Project.
Campaign donations: Groups supporting the initiative have raised more than $2.2 million, with most coming from Kelly. No campaign finance information has been filed with the state by groups opposed to the initiative.
