I remember listening to all this on the scanner during the DNC 2000 convention...when the US Secret Service ordered LAPD to disperse the crowd after DNCers were being assaulted. If you remember, a liberal judge let the protestors move to within 50 feet of Staples Center the few days before the convention.
