Holert analyzes the politics of visuality in the post 9/11 context (with reference to the theories of Walther Benjamin, Michel Foucault, Roland Barthes, and others), which is characterized by fragmentation, mediatization, and governmental/corporate control. Holert suggests that the way images are used as ‘evidence’ and ‘documenation’ by the powers that be show how they play a key role in the maintenance of power that Foucault called ‘governmentality.’
