Establishing a professional police must be taken through various stages of education and
experience. In carrying out their authority policemen are framed by a code of ethics to prevent
any interference from any party. But in fact this ethic code frame could not work optimally for
monitoring police performance because there are still many irregularities committed by the
police officer themselves. Deviations that occur in law enforcement, especially those conducted
by police officers happened due to the lack of awareness that the authority being given is a moral
responsibility to uphold the law, and by doing so is the requirement for law supremacy. How to
control crime which is committed by members of the police department? What obstacles are in
the prevention of criminal acts which are committed by the members of the police department?
To answer these two questions, the writer applied a normative legal research methods. In
addition to the application of criminal sanctions and ethic codes, the prevention efforts are also
supported by the program of activities such as: mental and spiritual guidance, technical
guidelines direction and supervision which are expected to improve police department
performance and professionalism as well as fix their deficiencies as an organization in line with
the spirit and ideals of police department reformation. The writer gives some suggestions. Firstly,
there is a need to increase the quality of education / training within the police department
environment to maximize performance and professionalism of its members in order to minimize
the violations and errors in the field. Secondly, the public is also advised to understand the
process of criminal law enforcement, particularly against members of the police. Thirdly, related
to the Police members' welfare problem which has been a factor that lead to violations, it is
advisable for the government to improve the welfare of members of the police department. Last,
the continuous cooperation between police and non-governmental organizations that specifically
deal with the police department to fix the deficiencies that become police problems.
