江总书记在“5·31”讲话中把坚持执政为民作为贯彻“三个代表”要求的本质。本文从公安机关的性质、宗旨、职责等方面 ,提出公安机关学习贯彻“三个代表”和执政为民的要求 ,重点要结合公安工作实际 ,牢固树立“执法为民”理念。 In his “May 31” speech, General Secretary Jiang held the governing of serving the people as the essence of implementing the requirements of the “three represents.” This paper puts forward the requirements of public security organs studying and implementing “Three Represents” and governing for the people from the aspects of the nature, purpose and responsibilities of public security organs. The key point is to firmly establish the concept of “law enforcement for the people” based on the actual work of public security.
