Since 2017, the Beijing public security team has been continuously trying to deepen the construction of law enforcement standardization, creating a "detention center for property", upgrading the "police station functional area" and "service window for the people", and striving to improve the level of rule of law and law enforcement credibility in public security work. Beijing Public Security has found a breakthrough in the optimization and upgrading process of law enforcement venues, integrating the idea of improving public trust into every aspect of law enforcement venues, and striving to make the spirit of the rule of law visible and tangible. At the beginning of 2022, a suspect in an economic crime insisted that an account book was lost when questioned by the prosecutor's office. This means that there are flaws in the evidence chain, which may lead to a deadlock in the handling of the case. There are hundreds of large boxes of documentary evidence involved in the case, and one of them is not there. How can we start investigating? The Changping Branch of the Beijing Public Security Bureau is responsible for the management of the involved property (hereinafter referred to as the "Changping Financial Center"). Here, the people and objects involved in the case go through a closed-loop process together. Each item involved in the case will first come to the involved property management office when entering the Changping Financial Center. Financial police officers will receive the information on the spot, scan the code, input the information, attach special labels, upload the data to the intelligent management system of the involved property, and promptly store the items in the intelligent storage cabinet. After the property involved in the case is stored in a standardized manner, the police will inspect the approval content of legal documents item by item according to the early inspection and late settlement work system of Changping Financial Center. In the face of detailed traceable circulation records, clear visual materials, and other evidence, the lie of the suspect's account book loss was exposed. The Changping Financial Center was completed in January 2022. The journalist was deeply impressed by the 5500 square meter footprint, 17 specialized storage rooms with various functions, and intelligent devices that arm from the ground to the ceiling. "The public is concerned about whether the things in the involved mobile phone are still there, whether the vehicle's equipment is available, and the property attributes of the property. The police are concerned about whether the data in the involved computer can be properly preserved in its original state, and about the evidential validity of the items," said Ruo Shaokui, deputy leader of the Legal Affairs Detachment of Changping Branch, "Regardless of which one, this' detention center for property 'can provide security." "Since 2017, the Beijing Public Security Bureau has been focusing on building a digital' detention center for property ', and has successively built 17 intelligent case related property management centers at the urban and rural levels, as well as 401 case related property storage rooms at grassroots level." Liu Yan, Deputy Chief of the Legal Affairs Brigade of the Beijing Public Security Bureau, introduced. The police station has established new functional areas, such as the case management consultation area, law enforcement supervision area, and comprehensive management area, at the Renhe Police Station of the Shunyi Branch of the Beijing Public Security Bureau. These areas serve as workplaces for the case management team's police officers. The case management team must carefully investigate and make judgments on all police cases they have encountered the day before, as well as appeals made by citizens through complaint hotlines. "This means that if the police officers in front make judgment errors due to limitations in on-site conditions and other reasons when dealing with police situations, the case management team can promptly and effectively make up for them," said Liu Boxiang, Deputy Director of Renhe Police Station. At 7 o'clock in the morning, when the reporter arrived, the police officers of the case management team were already analyzing a bizarre police situation: two people were knocking on the door of a residential building for an hour. The police arrived at the scene after receiving the call,
