Abstract:From the scientific principle, the controlled delivery belongs to the secret detection measure, and is paralleled with identity concealed and technical ones. We should design in detail the applicable conditions of such delivery. And through the further perfection of legislation, exploring the system of Report on Controlled Delivery to remedy the deficiency of proce- dure design, standardizing the evidence application and establishing supervision and relief, we can solve some practical prob- lems in implementation of procedure and specific systems.
