ALBANY – The Cuomo administration has opted out of the Adam Walsh Child Protection and Safety Act—a federal law designed to toughen and standardize sex offender registration practices—concluding that it would cost more than it is worth while undermining the state’s traditional protections for teenage offenders.

In a recent letter to the U.S. Department of Justice, the state said it would not embrace a law it was supposed to adopt more than two years ago.
