A breaking report from on the ground in Tunisia on the filtering topic at the World Summit on the Information Society: the Expression under Repression session and a phalanx of secret police who showed up.

In case you missed it, here is the freshly-released, extensive ONI report on Internet filtering in Tunisia. The short form is, as expected, the filtering regime is extensive and sophisticated, and includes political speech, blogs, and many other forms of online content, each replaced in the user experience with a misleading 404 error block page.

Clark Boyd of the BBC has an excellent report today, citing ONI’s Derek Bambauer and Nart Villeneuve.
