Jonathan Chait describes the litigators methodology of Glenn Greenwald:
You take a side, assume the other side is lying, and prosecute your side full tilt. It’s not your job to account for evidence that undermines your case — it’s your adversary’s job to point that out.
Bingo. My own encounters with Greenwald, in the comments to various blogs about the likelihood of Julian Assange being extradited from Sweden, have seen him follow exactly the same pattern: simply ignore any point which refutes something you claim.
This legal adversarial model makes for good justice, but bad politics.
