It is these types of situations in which members of local CSOs or other civil society actors engage in documentation as unofficial investigators. It is important to be aware that unofficial investigators are not protected in the same manner as official investigators. Moreover, contrary to professional investigators that are specifically deployed from abroad on a temporary basis, members of locally staffed CSOs will often remain in the physical proximity of the location of the violation during and after times of crisis. This makes them particularly vulnerable to retaliation. It is important to be aware of this and act accordingly, in a manner to minimize risks. For that purpose, this section focuses on the security of those who know, handle, and keep information on human rights violations and the confidentiality of stored information. 191 Dublin Core metadata initiative, User Guide/Creating Metadata, (Jan. 6, 2012), available at http://wiki.dublincore.org/index.php/User_Guide/Creating_Metadata#Language. 192 Note that the protection of persons is a responsibility that falls primarily upon States. 193 See for instance Ola Engdahl, Protection of Personnel in Peace Operations, 10 JOURNAL OF INTERNATIONAL PEACEKEEPING 53 (2005) with regards to peace operation missions. 124
