Part 4 129 on particular characteristics, such as their physical appearance and ethnicity, are not sufficiently grounded. Some countries, especially those where jury trials are used, have very strict laws concerning anything that could possibly affect the outcome of a trial. Public statements that have too great a prejudicial effect can result in judges dismissing charges on the grounds that it is impossible for the accused persons to get a fair trial. The identity or any personal information about the witnesses and victims of a terrorism-related crime should not be disclosed in the media, in order to ensure their security and protect their privacy. Key points – Part 4: • Taking appropriate measures to protect the security and integrity of investigations and intelligence databases is essential in ensuring the protection of human rights and the effectiveness of investigations; • Law enforcement agencies in terrorism-related investigations are accountable to the state (the legislature, the executive and the judiciary) and to civil society and the media; • Accountability contributes to creating trust between the public and law enforcement agencies; and • Accountability helps to ensure that law enforcement actions and operations are effective.
