Your question shows why people should never talk to the police without an attorney present.
It sounds like you're talking about a change to Penal Code 290.46, which allows people convicted of certain sex offenses to request removal from the California sex offenders website. You would only be required to submit a Static-99 -- which is used to determine the likelihood that you will commit sex offenses in the future -- if you make that sort of application.
You should NEVER volunteer information to law enforcement about your offense, except for the basic information required to register as a sex offender.
Beginning January 1, 2012, a registered sex offender will not be removed from the Megan's Law website unless a State-Authorized Risk Assessment Tool for Sex Offenders (SARATSO) deems the individual a "risk level of low or moderate-low." An attorney can help you apply for removal from the website, including the help of an expert qualified to conduct the SARATSO if you wait until next year for relief.
