Members of the Daves talking to Defalt and Clara
The Council of Daves were the leaders of DedSec and were part of side missions in the Watch Dogs: Bad Blood DLC. Raymond Kenney helped them when one of their members betrayed them. They also rejected Defalt as a member of DedSec. They wear masks that cover their entire heads in order to hide their identities. They also apparently have access to the CTOS, as when profiled their information is hidden and/or changed.
