The American Civil Liberties Union of Kansas is urging the Kansas Supreme Court to uphold a judge's finding that the state's criminal offender registry is unconstitutional.
The registry includes sex offenders as well as people convicted of certain violent crimes and drug offenses.
The ACLU said in a filing yesterday that instead of improving public safety, the registry laws impede offenders from reintegrating into a community.
The arguments come in a lawsuit filed by a child molester seeking to have his name removed from the Kansas offender list.
Shawnee County Judge Larry Hendricks ruled a law extending his registration requirement was a punishment that couldn't be retroactively enforced under the U.S. Constitution.
The National Center for Victims of Crime says upholding the ruling would "profoundly affect" victims.
