"The After Party" is a documentary feature film about a
journalist who is caught in a mass arrest while filming
a protest at Ground Zero. His film crew's videotape of
the incident leads to a civil rights lawsuit, uncovers
a police spying ring and launches his personal investigation
in to the weird world of domestic surveillance. With
special appearances by Andre '3000' Benjamin, Barack Obama,
The Bush Twins, Cornel West, Al Sharpton and Don King.

The protest that resulted in 1800 arrests was during the 2004 RNC Convention in NYC that brought what some lbo-talk participants reported as 500,000 people to the streets.
