It is hard to imagine, but litigation stemming from claims by protesters arrested during the 2004 Republican National Convention is ongoing. A federal judge has just ordered the release of 2,000 pages of documents relating to pre-convention surveillance.
The NYPD engaged in a substantial covert surveillance operation during the 18 months leading up to the convention. Some of the surveillance activity took place overseas. Pre-event surveillance has become a common "militarization" tactic in recent years, particularly since the September 11, 2001 attacks.
