Legal analysis: lawyers have no right to read papers during the investigation stage. They must go to the public security organ to complete the investigation and hand over the case to the people's procuratorate. At this time, lawyers have the right to read papers so as to understand the case and defend. Nothing is certain at the investigation stage. Whether the criminal suspect's statement is true or false requires the investigation organ to collect other evidence to verify it. A confession confirmed by evidence can be used as evidence, and a confession without evidence has no evidential significance. It is reasonable that the investigation organ is unwilling to show the matters under investigation to the lawyer.
Legal basis: Criminal Procedure Law of People's Republic of China (PRC).
