An interesting commentary by David L. Hudson Jr. on First Amendment Center.

Registered sex offenders would be banned from Indiana public libraries if Rep. David Yarde has his way.

This month Yarde introduced H.B. 1100, which would create the criminal offense of “sex offender library trespass.”

The measure provides: “A registered sex offender who knowingly or intentionally enters a public library commits sex offender library trespass, a Class D felony.”

Seems the only exception to the violation is for voting.
