My question involves criminal law for the state of: missouri took alfred plea at age 19 for sex offense in early eighties by 1988 my sentence was served. in 1995 was told to register as sex offender.I did until missouri supreme court ruled I was exempt do to retroactive laws. Then when sorna came into effect because of attorney generals ruling that all sex offenders must register regardless of date of conviction. Have never been in any trouble with law since conviction 29 yrs. ago.Can I do anything to keep from registering.
