Witness  is a group that focuses on the use of video and storytelling for citizen media activists to share information on human rights abuses.
On March 28th, we host a #GVFace  with Bukeni Waruzi  and Matisse Bustos Hawkes  of Witness to talk about tips on using video for advocacy. Here are some of their tips sheets  and toolkits for video activists:
