Moe Dubois proposed that the state require all sex offenders carry a distinctive drivers license or state-issued card that would be branded with a special mark indicating that person had been convicted of a sex crime.
Members of the California Senate Transportation Committee voted to reject the proposal Tuesday because members had concerns about how it might brand people who committed minor offenses.
They also felt the plan didn't address what would happen if an offender did not comply with the law.
Dubois believed special IDs could help police protect children from people like his daughter's killer, John Gardner, by quickly identifying sexual predators.
The idea of a state branding ID cards is not new. In Delaware, sex offenders get a new drivers license after release from prison marked with the letter "Y" designating them as someone convicted of a sex crime.
In Louisiana people convicted of certain sex crimes are issued licenses with "SEX OFFENDER" printed in bold on the ID.
