Abstract
The present article sought to analyze the context of the limits and obligations of state responsibility from the moment the agent represents the state, focusing on police officers, but encompassing the broader server. From the principles, especially that of impersonality, it is possible to verify on what the public agent is based for the security of his performance. Also, the development with regard to the state responsibility in the scope of its activities purposes, which are public services, which, as well as public security, has the duty to be provided by the state, but not forgetting that even if there is the service being offered to the administrated, caution is necessary, because the conduct perpetrated is not exclusively the responsibility of the public agent, but should fall, in most cases, to the Public Administration, even if the public security server is protected from exclusion of unlawfulness or compliance with legal duty.
