On May 29, 2008, officials began looking at the ruins of thousands of schools that collapsed. They were searching for clues about why they fell down. Thousands of parents have said the government and builders did not build schools properly. Many other nearby buildings were not damaged. Parents of children killed in the schools say they have yet to receive any reports. Local officials told them not to protest but the parents demonstrated and demanded an investigation. The government censors have stopped stories of badly built schools from being published in the media. There has been an incident where police drove away the protestors.
