funny you mention this,just last night on the news they were talking about how they want to make the sex offender laws even tougher here in iowa,the police in sioux city basically said because of the 2000 ft rule for day cares,schools,library etc,that the whole city was off limits for them to live in.but yet according to the law it was not against the law for them to be around these locations,they just couldn't live within 2000 ft of them.and because the law was so strict most of them were just giving the police false address'es.making it tougher to track em.
