California officials are poised to relax regulations that prevent sex offenders from living near schools or parks. The state corrections department is planning to change its ban following a Supreme Court ruling that says the general prohibition it too stringent when it comes to regulating where sex offenders can live.  The revised rules will be imposed only on pedophiles and others whose crimes involve children. The changes are expected to reduce the number of transient sex offenders. The department says it will take two months to review the registry to decide who will still be subject to the law.
