From the Irish Times:
Breivik had asked for an open hearing at which he wanted to dress in uniform. It was clear from a manifesto he published online to describe the planning and motivation of the attacks that he was looking for a platform for air his belief that Europe must be saved from what he describes as Muslim colonisation. He has also said that the killings themselves were “marketing” for the manifesto.
