Mark Wallinger's State Britain installation at Tate Britain was a rare example of a poised and poetic response to the curtailing of
civil liberties that have taken place during the Iraq

drag the discussion
into the realm of art without compromising their efficacy as works of art (Alfredo Jaar «s and An - My Lê's works operate on similar levels).
