How do i change a law or ordinance?

Short term for your specific problem you should apply for a governors pardon and with your desire and attempts to better your self they will most likely grant it, for legislation contact a Senator or Representative from the district you live in with a proposal for a change, it is doubtful that they will listen unless you have some signatures from other members of the community expressing an interest in the new legislation. For short term go for the Pardon.}{
