Rage Against the Machine, a Los Angeles rock band, took the stage Monday evening at the designated protest area near Staples Center. After its concert ended and a second band played, trouble erupted. A timetable, with approximate times, of key events:
* 5 p.m. Crowd of about 600 has formed around the stage. It's made up mostly of Rage fans, not protesters.
* 6:15 p.m. Marchers begin to arrive in the protest area.
* 6:45 p.m. The band takes the stage; lead singer Zack de le Rocha criticizes Democrats and Republicans, talks briefly about the crowd's right to protest. Group opens with "Fools on Parade." Among other songs: "Testify," 'Guerrilla Radio," "Killing in the Name."
* 7 p.m. The crowd pushes forward as the band keeps playing. Police helicopters hover overhead and officers gather nearby.
* 7 p.m. About this time, away from view of most concert-goers, a black-shirted anarchist climbs the fence separating Staples from the protest area. Police fire pepper spray at him; protesters throw bottles at police. The scene is calmed down as concert continues.

* 8:24 p.m. Police at Olympic Boulevard and Figueroa Street begin using their batons on people filing out there. Not all the concert fans have left, and several are pushed over or struck by rubber pellets in the process. Many of these people run west along Olympic Boulevard. They are chased by police firing rubber pellets and beanbags.
* 8:28 p.m. Officers on horses sweep north. A crowd of about 400 is caught between pellet-firing police on Olympic Boulevard and the mounted police heading north.
